[Solved] Tomcat on Icedtea only answers during shutdown?!

[Cygon]

I'm setting up a new Gentoo server on which I plan to run Jenkins (a Java webapp) through Tomcat.

At first, everything worked fine - I've set up the tomcat instance, the host manager showed, I installed Jenkins and it launched without a hitch. Then I restarted Jenkins and things went downhill from there:

- First, Jenkins (the deployed webapp) would not complete its restart
- Tomcat manager app showed 5 sessions and would time out when I hit 'Stop'
- After restarting tomcat itself, the Tomcat manager app still showed 5 Jenkins sessions
- After hitting 'Stop' a few times, the Tomcat manager app stopped responding
- Even after restarting tomcat, I get no HTTP response from Tomcat at all
- ...except: during shutdown. If I issue an HTTP request and then shut down Tomcat, it will be served.

I have erased every trace of Jenkins, I have removed and recreated my tomcat instance, I have restarted the server and nothing changed.

I've set all Tomcat logging options to 'FINE' (meaning debug/verbose). There is nothing useful at all in the logs. Normal startup without errors, tomcat process is running, HTTP requests time out & do *not* get logged. If I shut down Tomcat while a HTTP request is still waiting, then it does get logged.[/code]

Observations:

- it's running fine on another server, though that one is x86
- very sporadically it does begin to work. One running, it's fast and reliable.

- here's one instance of it suddenly starting to work after doing nothing for 8 minutes with 0% CPU usage.

Okay, it really was my system running out of entropy.
