[21:25:57] <jmtran> bjagg: For the News Reader portlet, did it run out of database connections randomly or under high load ?
[21:27:23] <bjagg> Report was it consistently ran out of connections under load after 2 hours in production
[21:28:41] <jmtran> Okay
[21:29:38] <bjagg> have you seen the issue randomly?
[21:30:15] <jmtran> No. I was wondering what caused it to run out of connections
[21:31:04] <jmtran> We had an odd case with the Announcements portlet where it ran out of connections randomly, but that was last year and I think it's been resolved
[21:31:53] <bjagg> Before the changes, the connection pool was using defaults, which is 8 connections max
[21:33:07] <bjagg> Since KU uses News Reader heavily, I think lack of caching and the lower max had them hitting the limit
[21:33:35] <bjagg> I have added caching and the connection max limit is significantly higher
[21:34:13] <bjagg> Plus I switched the pool with more explicit/forgiving config values
[21:34:32] <bjagg> Would love to convert all Jasig portlets to Tomcat connection pool
[21:36:04] <jmtran> I see

[21:37:16] <jmtran> I'm seeing these in our non-production env. Before I go investigating, anything come to mind ?
[22:05:45] <bjagg> This is from version 4.1.2?
[22:07:24] <jmtran> 4.1.3-SNAPSHOT
[22:10:51] <bjagg> No clue at this time. Might be a version issue.
[22:12:45] <bjagg> When you deployed (to Tomcat?), did you stop tomcat, deploy & delete TOMCAT_HOME/work/Catalina/localhost/NewsReaderPortlet before restarting?
[22:13:46] <jmtran> Didn't delete work/ ... I'll try that out in a bit
[22:17:44] <bjagg> Just checked my logs -- didn't see those WARNings
[22:18:12] <bjagg> But certainly better to track those down now rather than production :)
