tomcat 3.2.3 hangs, AIX 4.3.3 (jre 1.2.2 and 1.3.0)
Hello...
I have a problem which I can't resolve: tomcat "hangs" after some time (may
be 3 minutes or 2 hours).
I mean tomcat is running ("ps" shows it), but no answer is received to
requests when tomcat hangs.
Strangely, problem occurs only on _some_ of AIX 4.3.3 machines where I run
tomcat.
It happens either with ibm's jre 1.2.2 (with different builds) or 1.3.0,
and tomcat 3.2.3.
Some machines, with SAME jre/tomcat/code, run with no problem :-(
And I did not met that on winNT4.
Note that I got a javacore twice, if somebody can interpret it...
I searched in bug list, and it looks like bug 1006
(<http://nagoya.apache.org/bugzilla/show_bug.cgi?id=1006>),
or like problems described in
<http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg19652.html>
or in
<http://www.mail-archive.com/tomcat-user@jakarta.apache.org/msg16676.html>.
Since bug 1006 is said to be fixed, I don't understand what happens.
Does somebody can help, or give tricks to diagnose?
Thanks

In bug #1006 it suggests:
kill -3 <process-id>
*** The bug report also says that this command is for IBM JVM and Linux 6.2 (if I remember correctly) ***
This gives a stack-trace dump of all the threads. Looking at that may give you a clue as to where and why the threads are hanging.
