The usual cause is pool exhaustion, due to improper coding in a webapp that fails to return connections to the pool under *all* circumstances. > Nothing else has the lock Irrelevant. > I googled the problem and found a few other people who had > the issue, and there problem was related to GC. Highly unlikely; sounds like finger-pointing. > I see the 'from space' is at 99% used, as is PSPermGen object space. Not true in either case. You've used up 99% of what was *allocated* for the particular space at this time, not 99% of the maximum. You're nowhere close to filling up any region of the heap. > Do you think this could be causing my problem? No. If you had bothered to tell us the version of Tomcat you're using, we could have told you the proper documentation to read about how to use a connection pool. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
