RE: problems starting/stopping tomcat
Howdy, Use netstat to see the status of ports. Tomcat uses at least two ports at runtime: the SHUTDOWN port (8005 by default) and the actual user connector ports (8080 and 8009 by default for tomcat 4.1.x). What likely happened was: - Your first tomcat instance (ports 8005 and 8080) did not shut down properly, most likely because you had non-daemon threads still running - When you changed to port 8081 and tried to start, you got the error because tomcat was still listening on port 8005 for shutdown. You need to change both ports, or better yet, fix the cause for tomcat not shutting down properly ;) Yoav Shapira Millennium ChemInformatics -Original Message- From: Astrid Wagner [mailto:[EMAIL PROTECTED] Sent: Saturday, September 13, 2003 4:33 AM To: [EMAIL PROTECTED] Subject: problems starting/stopping tomcat Hi , I use tomcat 4.1.24, jdk 1.4.0 and Apache 1.3 on Solaris 8.

RE: problems starting/stopping tomcat
Howdy, I'm glad you're OK for now ;) Tomcat shuts down properly under normal circumstances. The only times when it doesn't is when webapps start non-daemon threads and don't terminate them properly. Sometimes your webapp doesn't do this directly but a 3rd party library used by your webapp does.

RE: problems starting/stopping tomcat
Howdy, Several things to do: Try to start tomcat from the console (use catalina.sh run instead of catalina.sh start) and when you run into this condition again, use CTRL-BREAK to send a SIGQUIT to the JVM so that you can an output of what your threads are doing. Don't start non-daemon threads in your webapp. Alternatively, if you do, make sure they properly handle interruptions and quit. If you're not sure where they're coming from, do the above SIGQUIT approach to see. As another alternative, though dirty and potentially very bad if there's more than one webapp on the server: write a ServletContextListener that does System.exit(n) at the end of its contextDestroyed method ;) Yoav Shapira Millennium ChemInformatics -Original Message- From: Astrid Wagner [mailto:[EMAIL PROTECTED] Sent: Monday, September 15, 2003 12:56 PM To: Tomcat Users List Subject: Re: problems starting/stopping tomcat Hi, Not again !!

Re: problems starting/stopping tomcat
Hi, I killed some processes related to native c calls I submit and now I can start/stop TC so this time it could have been some non-terminated processes (due to network problem). The question now is: I may have some situations like that e.g due to a network problem a native call can not be finished etc. How do I avoid running into such severe problems: do I have to implement sth. like a timeout in the c programm to guarantee it will quit ?!

RE: problems starting/stopping tomcat
Howdy, The general answer is, if you use a 3rd party library (in java, or c, or whatever), it is your responsibility to ensure that library shuts down properly. The container can't do that for you. In this specific case, how are you invoking the c library? If you can change the library's code so that it always returns/quits after a certain timeout, that's good. Alternatively, if you invoke the library in a separate thread, keep a handle to the thread, and interrupt it so that it returns from its run() method when you're shutting down.

The question now is: I may have some situations like that e.g due to a network problem a native call can not be finished etc. How do I avoid running into such severe problems: do I have to implement sth. like a timeout in the c programm to guarantee it will quit ?! Thanks for your help. Astrid Astrid Wagner wrote: Thanks for the quick response. Shapira, Yoav wrote: Howdy, Several things to do: Try to start tomcat from the console (use catalina.sh run instead of catalina.sh start) and when you run into this condition again, use CTRL-BREAK to send a SIGQUIT to the JVM so that you can an output of what your threads are doing. I ran catalina.sh run and run into this condition over and over. I do not know when/how I should terminate it since it prints out the message and finishes itself quickly. Should I look for java thread processes? Don't start non-daemon threads in your webapp. Alternatively, if you do, make sure they properly handle interruptions and quit. If you're not sure where they're coming from, do the above SIGQUIT approach to see. I am not aware of non-deamon threads. Maybe the problem has sth. to do with native calls I use but they are terminated I guess ... Thanks Astrid As another alternative, though dirty and potentially very bad if there's more than one webapp on the server: write a ServletContextListener that does System.exit(n) at the end of its contextDestroyed method ;) Yoav Shapira Millennium ChemInformatics -Original Message- From: Astrid Wagner [mailto:[EMAIL PROTECTED] Sent: Monday, September 15, 2003 12:56 PM To: Tomcat Users List Subject: Re: problems starting/stopping tomcat Hi, Not again !! I ran into the same problem: SEVERE: Error initializing endpoint java.net.BindException: Address already in use:8080 at org.apache.tomcat.util.net.PoolTcpEndpoint.initEndpoint(PoolTcpEndpoin t .jav a:280) at org.apache.coyote.http11.Http11Protocol.init(Http11Protocol.java:150) at org.apache.coyote.tomcat4.CoyoteConnector.initialize(CoyoteConnector.j a va:1 117) at org.apache.catalina.core.StandardService.initialize(StandardService.ja v a:57 9) at org.apache.catalina.core.StandardServer.initialize(StandardServer.java : 2246 ) not being able to get a clean state. Can you tell me how to look for status of ports and how I can kill those processes keeping thoses port occupied because I can not see tomcat process. netstat | grep 8080 returns nothing (I get sth. for 8005) but that is not why it fails??! I do not want to boot everytime I run into that problem .. Thanks Astrid Shapira, Yoav wrote: Howdy, I'm glad you're OK for now ;) Tomcat shuts down properly under normal circumstances. The only times when it doesn't is when webapps start non-daemon threads and don't terminate them properly. Sometimes your webapp doesn't do this directly but a 3rd party library used by your webapp does.

We rebooted the machine and until now (I keep my fingers crossed) it works again. Tomcat must have not shut down properly leaving me in a deadlock. Astrid Shapira, Yoav wrote: Howdy, Use netstat to see the status of ports. Tomcat uses at least two ports at runtime: the SHUTDOWN port (8005 by default) and the actual user connector ports (8080 and 8009 by default for tomcat 4.1.x). What likely happened was: - Your first tomcat instance (ports 8005 and 8080) did not shut down properly, most likely because you had non-daemon threads still running - When you changed to port 8081 and tried to start, you got the error because tomcat was still listening on port 8005 for shutdown. You need to change both ports
problems starting/stopping tomcat
Hi , I use tomcat 4.1.24, jdk 1.4.0 and Apache 1.3 on Solaris 8. After having developed and successfully run many servlets I now receive a port 8080 already in use problem after I try to start tomcat.

Could it be that while doing shutdown-startup sequences a process has been left hanging (?). When I replaced port 8080 by 8081 I was able to start tomcat but when I called a servlet it said 8005 (port for shutdown) in use ?! When I replaced also 8005 for test purposes the servlet hangs and I could not see any error being logged (catalina.out, web appl log files, Apache log ...). My question: how do I get more info about what ports tomcat still uses for what ? Any hint would be appreciated. Thanks. Astrid
