Runaway tomcat4 java processes

[TDuncklee]

Every day or so my system has two java processes that totally consume a processor each. It stays that way until I manually kill each process. Here’s what top looks like:

last pid: 18173; load averages: 3.27, 3.23, 3.17 up 0+16:04:28 10:55:35
349 processes: 4 running, 344 sleeping, 1 zombie
CPU states: 2.7% user, 0.0% nice, 96.9% system, 0.4% interrupt, 0.0% idle
Mem: 442M Active, 1112M Inact, 287M Wired, 119M Cache, 199M Buf, 50M Free

PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAND
418 tomcat4 60 0 328M 45268K RUN 2 948:36 95.12% 95.12% java
421 tomcat4 60 0 328M 45268K CPU0 0 909:51 85.89% 85.89% java

I’m running FreeBSD 4.11 and Plesk 7.5.4. Anyone know what is causing this or what java is doing with all that cpu time?

Thanks,
Tim
