Just recently starting with IU-94.585 and IU-94.633, I started getting more VM crashes on Ubuntu 9.10 64-bit and JDK 1.6.0_18. What was strange to me is I have been running this exact same configuration with the same idea.vmoptions for almost 6 months now and it had been very stable with very infrequent crashes. But starting with IU-94.585, I started to see more crashes.
I tried invalidating my IDEA cache and restarting, but it still crashed. I thought maybe I didn't have enough PermGen heap or maybe it was due to the UseCompressedOops I was using, but IDEA crashed even when I made adjustements for those options.
I have kept compressedoops off to try to keep my JVM config as simple as possible. But today, the JVM crashed several times per hour which is not acceptable. I filed a submitted a bug report ot sun. I may have to switch my development environment back to windows to see if that is more stable, because I'm doing alot of development now and need a stable IDE.
