Grouper Users - Open Discussion List

[Peter DiCamillo <>]

I'm trying to track down a problem which results in the Grouper UI 
eventually becoming unresponsive. When I restart tomcat, it starts up 
without warnings or errors. However, the first time a web services call 
is made, this warning appears in catalina.out:

2013-04-16 23:29:09,775: [ajp-8009-1] WARN 
ActiveManagementCoordinator.attemptManageC3P0Registry(56) - A 
C3P0Registry mbean is already registered. This probably means that an 
application using c3p0 was undeployed, but not all PooledDataSources 
were closed prior to undeployment. This may lead to resource leaks over 
time. Please take care to close all PooledDataSources.

Is that something to be concerned about, and possibly the cause of my 
problem? I haven't tried enabling debug logging yet, but the only other 
unusual thing I see in the logs are some messages like this from time to 
time:

2013-04-16 23:29:20,927: [ajp-8009-1] WARN 
WsStemLookup.retrieveStemIfNeeded(208) - Invalid query: WsStemLookup[
  stemFindResult=INVALID_QUERY]

This is with Grouper 2.1.4.
