Description of problem:
When running Tomcat, at non-deterministic points, as far as I can
tell, the server simply hangs, does not accept incoming requests,
either on port 8080 or via mod_jk2. shutdown.sh does nothing. Unable
to kill process with kill PID, using kill -9 sometimes causes process
to go into defunct status. Restarting Tomcat fails with message that
ports 8080, 8005 are in use. Only recourse is to reboot the box.
In addition, various strange and similar things happen when running
other Java processes.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start Tomcat
2. Wait a bit
Actual Results: Tomcat frequently crashes and locks up the machine
Expected Results: Tomcat should not crash and not lock up the machine.
I'm using the JVM supplied with Fedora, but running a Tomcat install
from jakarata (not gcj, I believe). I tried running the Tomcat
available via yum/rpm, but had other configuration problems setting up
the security manager (unrelated, I believe).
Update: I'm cautiously optimistic that this bug is the same as #121902.
I should know in a day or so, if things continue to go well (fingers
Fedora Core 2 is now maintained by the Fedora Legacy project for
security updates only. If this problem is a security issue, please
reopen and reassign to the Fedora Legacy product. If it is not a
security issue and hasn't been resolved in the current FC3 updates or
in the FC4 test release, reopen and change the version to match.
FC1 and FC2 are no longer supported even by Fedora Legacy, and this bug refers
to tomcat version 4.x, last shipped in FC2. tomcat5 replaced it, and has quite
a few differences, so please retest the bug. If this still occurs on FC3 or
assign to that version and Fedora Legacy. If it still occurs on FC5 or FC6,
please reopen and assign to the correct version.
