We are having one of our servers crash almost daily and it appears to correlate to high memory usage. Here's the chart: In the chart, the system locked up about 6 pm which was when the call center was stopping for the day. The system was rebooted and that's where the red memory line went back down low. We turned off openfire because of the threads talking about its issues, but that only seems to have slowed down the problem-- not ended it. Ideas?
