Zimbra 4.5.10 Network Edition on MacOS 10.4 Server.
For the last few weeks I've gotten support calls that "the mail server is down" only to find that tomcat had stopped at random while all the other services had continued. This initially happened with 4.5.09 and I updated to 4.5.10 partially just to see if it would resolve the issue. As opposed to other tomcat-related issues I can find in the forums, tomcat will run for days for me without incident, and then just suddenly quit. This happened again this morning, and I'm attaching my catalina.out in the hopes that maybe someone will be able to make sense out of it. Any thoughts?
