About once a month, the WebAccess page starts to time out / stop responding. I am running GW2012 SP1.

I restart tomcat (rcnovell-tomcat5 restart), and then it works again.

When I look at /var/opt/novell/tomcat5/logs/catalina.out, I see the following:
2013-02-26 12:44:24,559 [TP-Processor4] ERROR org.apache.tomcat.util.threads.ThreadPool - All threads (200) are currently busy, waiting. Increase maxThreads (200) or check the servlet status
That is the last line in the log until I restart Tomcat.

Is there some kind of memory leak in WebAccess, or are some threads never being closed?? If I look back in the logs, the first time I see this happening is in October 14, 2012. I'm not sure if we were running GW2012 SP1 at that point, but we were definitely running GW2012.
