Re: Apache Process going high even after restart of backend server tomcat
Thank you for the data below. Some additional tips : First : you are running old versions of Apache httpd, mod_jk and Tomcat (and probably also of the Java JVM). You should really update these programs to more recent versions (at least Apache httpd to 2.2.x, and mod_jk to the latest available). If you do not, then - whatever we tell you here may not be relevant for these older versions - you may have problems now, that are due to bugs that have already be corrected in later versions, and then this would all be a big loss of time, for you and for everyone else Maybe the very first thing to do, would be to have a look at your Apache httpd access log. Usually, this is configured so that each line shows a timestamp, the request URL, and the total time that it took to process this request. What does this log tell you ? From the Tomcat thread dump you posted, it looks like there are a lot of threads just sitting there sleeping, instead of being busy processing requests. Are those the threads that should be processing the requests ? And if so, why are they sleeping instead of doing their job ? - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

running tomcat with a website wich is not the IIS-default website
Hi, since a few years i am using the tomcat (Version 4.1.30 on a Win2K-system) in connection with iis via the isapi_redirect.dll. Everything was great but now i have a big problem: iis serves the IIS-defaultwebsite and a few others and servlets were only used in connection with the default website. The new situation is, that there is a need to have servlets also with one of the other websites. Reading documentations did not help - i found nothing in connection with my problem. So the first idea was to add the isapi_redirect.dll to the other website. The arrow got green and everything seemed ok - but nothing happens which means that it is not possible to call servlets on the website which is not the default. Whats wrong??

Re: Possible race condition with mod_jk + multiple workers in recovery mode
On 12.01.2011 00:59, Andy Wang wrote: I'm not sure, but it looks like the service() function in jk_lb_worker.c calls puts a recovering worker into the JK_LB_STATE_PROBE state and then doesn't set it to JK_LB_STATE_OK until after the end-service() call. I think this allows a second thread to come in, and since JK_WORKER_USABLE() returns false because of the JK_LB_STATE_PROBE state it never tries to use that worker and the second request thread completes, then the first request completes and finally marks the worker as JK_LB_STATE_OK. Still working on a reproducible state to debug this in, but does this sound like a possible problem or am I mis-reading what the end-service() call does here: service_stat = end-service(end, s, l,is_service_error); That was meant as an improvement. Recovery is only used, when a worker has been in error state for enough time (by default 60 seconds) and we want to find out whether it is still in error or not. mod_jk has no active probing with test URLs, so if the 60 seconds passed it marks the worker/instance a recoverable. Then it waits for the next request which is eligible to be handled by that instance (either carrying an old session iformation pointing to that instance or being freely balancable), and sends it there, marking the worker as being probed. If it succeeds, fine we can set the instance to OK. If not the instance goes back to error and the request will be sent to some other OK instance. Most of the time an instance will be in error for longer time, so probing in parallel is not a good idea, e.g. if the error state leads to delays in request handling. OTOH if the worker is fine now, it should ususally respond very quickly, so the time window where request could have been handled by the worker but weren't is very small. This seems fine to me. All this will be nicer once we add a probing feature to the maintenance thread which will probe the erroneous workers via a background thread and recover the worker as soon as the probing succeeds.

tomcat won't start via remote ssh command
Hi Guys, I created a simple (i thought) script to restart a tomcat server when our alerting system sees the site as down (almost always a memory issue that a reboot of the tomcat server fixes). The script runs and works fine when executed as the user on the local server. When run via ssh, it will shut down the tomcat server, and appear to start it -- but does not. I'm not a tomcat expert at all and I haven't been able to figure out how to get more information. I'm guessing that there is some environment information that is missing over the ssh terminal that is causing it not to start, but I don't have any hints and the output is the same as when it works. The SSH command I run that doesn't work is below. Since even this command does not work, I won't bother complicating the issue with the details of my script: $ ssh -t -p 222 u...@tomcatserver.domain.com '/usr/local/sites/domain.com/domain-tomcat1-production/tomcat/bin/startup.sh ' Using CATALINA_BASE: /usr/local/sites/domain.com/domain-tomcat1-production/tomcat Using CATALINA_HOME: /usr/local/sites/domain.com/domain-tomcat1-production/tomcat Using CATALINA_TMPDIR: /usr/local/sites/domain.com/domain-tomcat1-production/tomcat/temp Using JRE_HOME: /usr Connection to tomcatserver.domain.com closed.
