They are in the same tomcat, and I can try that. There's no need for hot redeploys. Do you mean completely separate installations of tomcat, or one tomcat but using different values for CATALINA_BASE ?

Are you running the UI and WS in the same tomcat? Can you try running in

how we run it at Penn :) This isn't a dev env where you are doing hot
redeploys, right?

Subject: [grouper-users] Tomcat warning for c3p0

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[

This is with Grouper 2.1.4.
