Re: tomcat shutdown problem with axis webapp

[Richard Martin]

This is a difficult problem to diagnose remotely. The 1.4.2 release 
changed the way that the linux JVM handles threads in a significant way. 
Threading was tweaked and prodded to get Native Postix Threading Library 
(NPTL) support and the associated performance increase, so it's very 
likely that, if there were any bugs with JVM Thread destruction, they 
would have been sorted at this time.

As for a solution - 1.4.2 is a much better environment for thread 
programming; use it if you can.

Richard

Subject: tomcat shutdown problem with axis webapp

 

Shutting down tomcat with the axis webapp installed causes tomcat to not
   

shutdown fully, leaving many java threads runing that require issuing a
'kill -9 ...' in order to restart tomcat.
 

New installation of tomcat 4.1.30, new installation of axis 1.1 final
   

release.  No conf changes, just copied the axis subdir under webapps to
tomcats webapps dir and restarted tomcat.  $JAVA_HOME set to use jdk
1.3.1_09.
 

I've read a few similar posts but have not seen any solution for this
   

problem yet.  It's driving me crazy, so I'm beginning to wonder if it could
be Linux distro related.  We have an older Redhat 7.1 distro at work we
develop on.
 

$ more /proc/version
Linux version 2.4.7-10smp ([EMAIL PROTECTED]) (gcc
   

version 2.96 20000731 (Red Hat Linux 7.1 2.96-98)) #1 SMP Thu Sep 6 17:09:31
EDT 2001
 

Interestingly enough, if I change my $JAVA_HOME to use jdk1.4.2_03
   

instead, this tomcat shutdown problem with axis leaving threads running goes
away.
 

Also, when I leave my jdk at 1.3.1_09, and just move the axis
   

subdir/webapp out of the tomcat webapps directory, the problem also goes
away.  So it's definetly related to the axis webapp.  But certainly
interesting that the 1.4 jdk fixes as well..but that causes other issues for
my app so I really want to run it with my $JAVA_HOME set to use jdk1.3.1_09.
I'm not quite certain why my local $JAVA_HOME jdk would cause any difference
on how tomcat/axis shuts down though.
 

Any ideas on what's causing this or how to fix?
Thanks!
