Hmm, I didn't see anything that jumped out at me in those logs, which
doesn't necessarily mean there isn't anything!
Don't you have a catalina log? Or at least a stack trace?

If you're connecting to an SQL DB it's possible that you're simply not
closing your connections to the pool, so after a certain length of time
(depending partially on what maxconnections you allow) tomcat would stop
responding - probably with a 500 error.
