jsvc.exec error: Service exit with return value of 122

[Jason Britton]

Running tomcat 6.0.29 using  jsvc on 64-bit RHEL 5.5.  Tomcat was happily
serving requests and then hung, checked log to find jsvc exec error below.

06/10/2010 08:24:38 16880 jsvc.exec error: Still running according to PID
file /var/run/jsvc_waw1.pid, PID is 5757
06/10/2010 08:24:38 16879 jsvc.exec error: Service exit with a return value
of 122

Any suggestions on troubleshooting would be greatly appreciated.  Thanks a
lot,

Jason
