Help with Thread Analyzer
|
|
|
| Problem background:
Websphere Application Server process is present after stopping the server. SystemOut.log shows the server as being stopped. It was suggested in this forum that a thread might still be running after the server stops. So I used kill -3 <process ID> to get a
javacore.....txt file.
I then used Thread Analyzer to view the thread dump. The Analyzer says that 37 threads are still present. (The server is stopped) I don't know how to interpret the analysis. I can provide the thread dump file to anyone who can help me with solving this i
ssue.
Thank you.
Environment: WAS ND 5.1.9, AIX 5.2, LDAP, SSL etc.
Kind Regards,
MPro

Even if you can identify the TID of the offending thread, that won't
help you resolve the issue. What you need to do is ask your developers
who is creating threads, and have them figure out a way to stop their
thread when the server (or application) is going down.

| Review the stacktraces to identify whose code is still running (WebSphere or
your application) and what exactly it is doing.
You can post the javacore to the newsgroup or somewhere on the web.
