From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0; T312461) Description of problem: After one month in production and several months running before that in test, the system suddenly hung-up, totally frozen, at 10pm at night on a very light load with kernel 2.4.9-12enterprise Version-Release number of selected component (if applicable): 2.4.9-12enterprise How reproducible: Couldn't Reproduce Steps to Reproduce: 1.No obvious way to reproduce this. No clues in any of the logs, the system just died. 2. 3. Additional info: A colleague thinks it might be a virtual memory management bug whereby the init processes gets swapped out. That would explain why there are no log entries. We do run certain system utilities such as vmstat and nothing strange shows up in cpu, memory utilitization or disk access.
Just checking back to see if you have any thoughts on this. By the way, the hardware is a Compaq Proliant 8500 8-way cpu with 4GB of memory. Would a kernel upgrade to 2.4.9-31enterprise be of any help?
Hard to say. There have been quite a few small fixes, some of which could explain a crash. Also around -21 we updated the cciss driver iirc....
Closing - no activity for a year, assuming fixed
