OK, so we can rule out OS patches as the cause ;) >I am also observing a significant memory leak on this >box, though I can't figure out if its Tomcat, java, >the code or something else - once the memory gets low >enough tomcat crashes. Once the memory gets low enough, the server will crash, yes. It's likely that if you find and fix the memory leak, your crashing problem will go away. >I am planning on making the following config changes >to hopefully remedy this problem: > >-Xms512m -Xmx512m -XX:NewSize=256m -XX:MaxNewSize=512m >-Xincgc Doesn't make sense at all. The new generation size should never be the entire heap, as that leaves no room for long-lived objects and will have your JVM thrashing all the time. If your machine has 2GB of memory, maybe something like -Xmx1024m -XX:MaxNewSize=256m is more reasonable. Experiment with incremental collection (-Xincgc) but don't expect it to be a miracle cure. Finally, if your memory leak is serious enough, your garbage collections settings may not help at all. Use a profiler to determine where and why the memory leak is happening, and fix it in the code.
