Frequent VM Crashes
The JVM on my computer crashes alot. (Meaning, I almost never get to keep my programs running for more than an hour unless I'm not using them while they run. Frequently the crash will occur while my programs, Eclipse/NetBeans are starting up.) Originally I noticed the problem using Eclipse, but as the problem seemed to get worse and worse, I switched to NetBeans IDE 5.0. (Reinstalling Eclipse always seemed to help, but the crashing would always get unbearable.) NetBeans ran great for a while, but exactly the same problem has been croping up again, and this time it's also crashing a significant amount of the time while running the programs I'm developing. I've never had this problem on any other machine, so I expect there's something curious about my computer, but I've run memory tests repeatedly and they've come up clean and I don't really have a problem running anything but the JVM. Here's a sample error dump:
