Morning all...
Late last week, I upgraded the INN news server running on my
box to the latest code, due to major changes in the XOVER code. Within
12hrs or so, the system hung solid. You could ping it, but nothing else.
Previous to the code upgrade, the server had been running consistently,
and without problems, since its last reboot.
I've included both the dmesg output, and the kernel config file
I'm using, and, according to uname -rv:
3.2-STABLE FreeBSD 3.2-STABLE #0: Tue Jun 8 12:56:16 EDT 1999
Basically, my attitude has been that if my machine crashes or
reboots, for whatever reason, take that day (its down anyway) to upgrade
to the newest -STABLE release, just to catch any bugs/instabilities that
may have been found since the last one.
Now I'm getting these hangs almost like clockwork...every 24hrs or
so. My impression has always been that a hang where you can still ping
the machine is a SCSI problem, so that is why I'm CC'ng the SCSI mailing
list...
I have 11 SCSI drives on that machine...if its a drive problem,
narrowing it down is going to be next to impossible without *some* sort of
help from the operating system.
I work in an exclusively Solaris shop at work, and one of the very
nice things about Solaris is that it will at least give you WARNING
messages if something appears off...if the machine is still pingable, and
if I have a serial console up, and assuming that there is some sort of
'race condition' at work, is there no way of having the kernel issue a
message to the console telling me that its having a problem talking to
drive rdaXs1X? Something to indicate that there is a problem and which
drive it suspects?
Thanks...
