Doubt in threads
Is there any possibility that tomcat 6 process threads will increase even in the idle state without working on any request. since if i check the tomcat thread by *ps -C java -L -o pid,tid,pcpu,state,args | grep tomcat6 | wc -l * in cent os after few hrs it get increased. Is it tomcat's behaviour or leak in application? Arvind S * Many of lifes failure are people who did not realize how close they were to success when they gave up. -Thomas Edison*
Re: Tomcat 5.5.23 stops listening to requests on SSL port
Thanks for the suggestion of taking a thread dump... I think I have some instructions on how to do this on a windows server. The apache httpd server is on a different machine to Tomcat, thats how they can both listen on port 8443. - Original Message From: Christopher Schultz ch...@christopherschultz.net To: Tomcat Users List users@tomcat.apache.org Cc: p...@pidster.com Sent: Friday, 1 May, 2009 18:07:42 Subject: Re: Tomcat 5.5.23 stops listening to requests on SSL port -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Rahman, On 5/1/2009 9:24 AM, Rahman Akhlaqur wrote: The SSL is terminated at the load balancers, so the request is then a http request on port 8443 to our apache webserver (we use this to resolve multiple hostnames to just a few virtual hosts) which then just proxys the http request to Tomcat. At which point we want the request to be passed on to the content server as a secure request on port 443 - to match content hosts set up on port 443. It seems to work okay as the reverse path is fine, from the content server back to the end user. This sounds fishy. You terminate SSL at your lb, so there's no SSL anymore, right? Tomcat is listening on 8443 (as per your Connector configuration) so how can your lb send the request to Apache httpd on port 8443? Maybe you just reversed the ports in your post. It sounds like you are doing this: client [HTTPS] - lb:443 [HTTP] - httpd (port?) - Tomcat:8443 (If you are expecting a previously-encrypted connection coming to Tomcat, why not set secure=true in your Connector?) There is nothing in the Tomcat logs, the request is not even logged in the localhost access log - this points to Tomcat not even listening properly on port 8443. The other port (8080) is working okay though. Have you taken a thread dump to see what is happening? Since you are running 3 connectors, you might want to use a shared executor to manage threads, though the result with no further changes will be that /all/ threads will likely be tied-up, rather than only those servicing port 8443. I highly recommend a thread dump to see what all your threads are doing. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkn7LF4ACgkQ9CaO5/Lv0PCG5ACfcuG/xvslTxhXzvfp25inr/at InMAoKOvUg5QSxowVKUhwBxk8kSft96z =VMmX -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: jk-to-tomcat multiple retries
On 01.05.2009 18:19, Dmitry Beransky wrote: We have the strangest problem started happening to us a few weeks ago (after several years of running pretty much the same configuration). 1. The problem is only happening in the production environment. We cannot reproduce it on staging, which as far as we can tell is configured identically to production. 2. The problem seems to be tied to the traffic volume and possible pattern (Hence probably why we cannot reproduce it on staging). 3. Our configuration: W2K server running IIS 6 and JK 1.2.27, Tomcat v. 5.5.12 running on the same box. The problem is as follows: some requests would result in multiple copies of the first buffer-full of expected data, ended either by a 503 error page data, a 502 error page data, or the rest of the proper page. The number of copies is directly related to the JK's number of retries setting. With the number of retries initially being set to 10, the maximum number of repeated copies in the response was 20. When we set the number of retries to 2, invalid replies contain only a single buffer-full of the page's proper data followed by an error page data. On the Tomcat side, these multiple copies show up as multiple request entries in the access log, while there is only one corresponding request entry in the IIS log. After a fresh restart of Tomcat, it takes a little while for this problem to start manifesting itself. With time, it is starting to affect increasingly more requests until finally Tomcat gets entirely locked up. At that point Tomcat needs to be restarted lather, rinse, repeat... Here's what a sample of error messages in JK's log looks like: [2760:2476] [error] jk_isapi_plugin.c (1199): WriteClient failed with 10053 (0x2745) [2760:4020] [error] jk_ajp_common.c (1726): Chunk length too large.

Yesterday I temporarily changed JK Tomcat configuration matching the packet sizes. The chunk errors went away, but the problem seemed to persist, so I put everything back the way it was. The chunk length message seems pretty weird. Looks like a protocol corruption. Those indicate, that you should really try a TC update. Concerining your restriction can't update before any other options are exhausted: there will never be any other options exhausted. But after some options are taken, the rest get more and more expensive, risky and with a low chance of success. To me this look likes some weird error condition in Tomcat has hit an obscure bug in JK whereby it doesn't clear the response buffer between retries. Has anyone encountered this issue before or is just willing to land a helping hand in troubleshooting? Not encountered this before, and I think noone reported a similar observation. Concerning retries: Could you provide your full configuration (e.g. retries for an ajp13 worker is something very different from retries of a load balancer worker).

Hi,
I wanted to send a application message like Application specific GUID to
the accesslogs, the GUID is generated by our system and it is not general or
available in the request or the response So i was wondering if there is
any way where we can send that message to the logger which will add it to
the Access log when it is logging the request?
The problem is that i am writing a parser to view the logs using chukwa, now
if i dont have this functionality, hence timing of the logging is an
issue(In case I do it seperatly in a diffrent log file) I might need to
wait longer to parse it.
The access log allows you to log session and request attributes via an
appropriate configuration of the pattern attribute:
%{xxx}r xxx is an attribute in the ServletRequest
%{xxx}s xxx is an attribute in the HttpSession
So you can either set the GUID as an attribute to the request object via
setAttribute, or put it to the session. I guess your GUID is request
specific, so you should use the request way of doing it. Choose an
appropriate name, that does not conflict with any other possible use,
like com.mycompany.myapp.GUID for the attribute (that's the xxx above).
Note: setting a request attribute has nothing to do with request headers
or query parameters. Those attributes are neither received from the
client, nor send to it. They are for internal processing means.

Rainer

I don't really understand that bit above about ..and also it has dhcp which assign the IIS server... So ignoring for the moment the part about DHCP.. What it sounds like you want to do above, is make Tomcat act as a proxy server for the IIS server. I don't think Tomcat can do that (easily), and in any case it is not something that Tomcat is really optimised to do. What you should probably use in this case, is something else that sits in front of Tomcat /and/ IIS, and distributes the requests to the appropriate back-end. You could do that easily with an Apache httpd server. client -- Apache httpd -- tomcatserver/index.html ? -- Tomcat -- iisserver/index.html ? -- IIS In Apache, you could use mod_proxy to forward what needs to be forwarded. You could also turn things around, and have your IIS server in front, forwarding to Tomcat when needed. Apache/Tomcat connectors, or IIS/Tomcat connectors, are modules that sit at the level of a HTTP server front-end (Apache or IIS), and forward requests to Tomcat (back-end). The AJP redirector (for IIS), the mod_proxy_http and mod_proxy_ajp and mod_jk modules (for Apache) are such Connectors. For example, in the schema above, they are at the level where you see tomcatserver/index.html ?. But they do not redirect from Tomcat to something else, it's the opposite. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Perhaps it will save someone else some pain. I have a Java Servlet calendar application. It's a stable app and I've got at least a thousand of running copies. I was attempting to install it on GoDaddy's shared Linux hosting service which runs Tomcat 5.0.27. Reading the documentation on their site, it looked like all I had to do was upload the WAR file and wait until 1:00 AM Arizona time and the application should be deployed. I did this and waited. The next day, I found the application had not deployed. A call to technical support revealed that I had to go to a certain corner of the hosting control panel and enable Java language support. I did that and waited until the next day. This is one of the problems with their shared hosting account. ANY change takes until the next day to take effect. The next day, I looked, and the WAR file had been exploded but my App didn't work. Since my App has a dependency on the database, I uploaded a simple JSP to test the DB Connection. It worked. Attempts to view the error logs failed. I called GoDaddy support. The technician told me I need to enable error logging. He walked me through the control panel and I enabled error logging. I waited until the next day. The application still didn't work. When I tried to view the error logs, I got nothing. Another call to technical support revealed that the error logs I had enabled would not actually contain any Tomcat log data. I had my call escalated to a manager. I explained to him the reason I knew my application was not working. I told him the login page was not available. His response was Yeah, there's no file with that name. I told him that the URL was a virtual mapping created in the web.xml file. After literally an hour, they came back on-line and told me that they were going to open a trouble-ticket and call me back. Several hours later, I got an Email from support saying. It doesn't work because there's no file with that name. At this point, I had a funny feeling. I created a simple WAR file with one servlet and a web.xml deployment descriptor. The deployment descriptor mapped three URLs to the servlet: /MapTest.xyz /MapTest.jsp /MapTest.html I waited until the next day. Sure enough, I could access MapTest.xyz, and MapTest.jsp. Attempts to access MapTest.html generated a 404 Not Found error. This explains why my application was not running. All my servlets are mapped into URLs with extension of .html. This was a design decision because customers generally want the maximum visibility to search engines. So, what I found is that GoDaddy.com does not pass all requests into the servlet container. It attempts to service as many requests with Apache first, and then only passes the non-mapped requests into Tomcat. There are some 50 file extensions GoDaddy co-opts including .css, .xml, and .js. This configuration actually causes their deployment of Tomcat to be non-compliant with the Servlet API version 2.3 specification. Section SRV.11.2.1 says that explicit mappings in the deployment descriptor must take precedence over implicit mappings. Taken as a SYSTEM, their deployment of Apache Tomcat is non-compliant. My feeling is that ANY request that maps to a deployed context must be passed to the servlet container. Clearly, they are not doing that. So, after all the effort, I get to tell the customer that my application will not work on their hosting account. Rats. In general, even if your application isn't using servlet mapping I can't recommend them. Since it takes until the next day before you can re-deploy a WAR file, and there are no Tomcat logs available, it would be a really rotten experience. -- George Sexton MH Software, Inc.
