Hi all, I seem to be getting an abnormal amount of crashes in RedHat lately. They seem to be fairly random, so I have been having a though time troubleshooting this one. This morning it crashed at 08:39. This time I was able to extract some information from the system log, but I'm having a hard time making heads or tails of it. It seems to start at 08:35 with a NULL pointer dereference, there's a kernel oops in the middle, and at 08:39 it crashes with the NULL pointer error. Does anyone know what this all means?
