Our Rollbase instance was hanging this morning. No one was able to login until I rebooted our servers. I checked the Catalina logfile and it appears that Rollbase ran out of memory. The logfile is posted below. What do you suggest we do to prevent this from happening in the future? Thanks.

Make sure your Tomcat memory heap size is set to at least 4GB. See screenshot here: http://www.coderanch.com/t/87422/Tomcat/increase-java-heap-size
...but use at least 4GB for both
marking as solved
