Hi, I know that you are not interested in vmware oopses, but I'll try anyway. Today I stressed machine a bit (204MB VMware session with 256MB of memory in host; about 40MB went to swap) and something went wrong... If anybody has some clue, what's wrong, please do not hide and tell me.
Machine is dual PIII/450, 256MB RAM, 18GB IDE. Usual workload is dnetc (distributed.net client) and mpg123. OOps happened when I was exiting from vmware, so it is possible that it is bug in vmmon module. But before I dig into that, I'll try to do someone else's problem from this ;-) Thanks, Petr Vandrovec vandrove@vc.cvut.cz
