you mentioned kernel 2.2.11? there is a nasty memory leak in the tcp
code... while we were on it, the machine would lock up about once every
36-40 hours. 2.2.12 cleared it up.

- linux-2.2.11-SMP with raid0145-990824 with four 2gb drives
- in a RAID-5. The SCSI bus is onboard Adaptec 78xx. The

-The problem? It locks up. Solid. I've never in my life

-currently completely unutilized at this time.

-It seems to lock hard every few days. Maybe 3 or 4? I see
-no coorelation of activity (ie, users doing something) and
-lockups, but am willing to dig a little deeper if someone has
-an idea.
-
-I was wondering two things:
- A. Are there any known incompatibilities with any of this
- hardware? I've seen some mentions of aix78xx, SMP, and
- raid causing problem. Is this what I'm bumping in to?
- B. Is there anything I can do to figure out WHAT is causing
- the hard lockups? Again, no hints in /var/log/messages or
- anywhere else. Possibly a serial cable to a dumb terminal
- constantly dumping system information?
-
-Any information or clues would be more then appreciated. Replies
-directly to the list are more then fine; I subscribe to both.
-
-Thanks.
