Funny kernel antics
On my Internet server (running potato and kernel 2.2.19pre), I got a funny
thing happening. The kernel started to spit out errors on the console. I
can't reproduce them, but they are the CPU dump of registers that you get
when unix normally crashes and then halts the machine. I kept getting this
dump, then I tried to shut down the machine, but couldn't. It was dumping
on qmail and apache processes and just causing havoc, although I could
still ping the outside world. I had to press the reset button to get out
of this situation. Luckily the machine came up ok.
Some symptoms include:
(a) I can't log in properly in the first console screen, but after Alt-F2
to the second screen, I can get in ok
(b) I have had the machine hang with the screen being blank..had to press
reset...this happens once every two
weeks. Logs don't show up any errors.
I had upgraded from the bo distribution to potato and suspect it must have
been something done during the upgrade, as I updated heaps of packages.
Previously, running on bo was very stable..hardly had a crash at all
Anyone know what causes this or seen this happen before?
I will probably install a fresh copy of potato on another hard disk and do
the config again, just as a backup :-)
