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(PoolTcpEndpoint.java:280) at org.apache.coyote.http11.Http11Protocol.init(Http11Protocol.java:150) at org.apache.coyote.tomcat4.CoyoteConnector.initialize(CoyoteConnector.java:1117) at org.apache.catalina.core.StandardService.initialize(StandardService.java:579) 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

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.

Thanks. 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.

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 ;)

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.

I did not change any configuration and I do not think that the ports are in use by any other processes (Apache uses a different port). 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.
