Symptoms
Seeing the following errors in the wrapper.log file.
JVM appears hung: Timed out waiting for signal from JVM.
ERROR | wrapper | 2009/02/23 03:39:39 | JVM did not exit on request, terminated
DEBUG | wrapper | 2009/02/23 03:39:40 | Waiting 5 seconds before launching another JVM.
STATUS | wrapper | 2009/02/23 03:39:44 | Launching a JVM...
Cause
This message usually occurs because your cpu is hitting 100% for around 30+ seconds.
See the article http://lists.hippo.nl/pipermail/hippocms-dev/2006-April/001488.html.
(Fisheye may use high CPU during the indexing process, or the high cpu may be caused by another application like svn).
Resolution
Try adding the parameter
to your wrapper.conf file, to increase the timeout period and thus prevent the JVM from being terminated. You will need to restart your server after setting this value.
