Hi All,
We've got an HP DL380 server, stacked out with drives running Sendmail. The
machine is quite busy (LA rarely below 4 - and it's three 'spindle' sets of
RAID drives are always busy). It's probably constantly running 200-300
copies of sendmail, plus an assortment of other processes (mostly admin
scripts that kind of thing).
It's got a Xeon 3.2Ghz CPU (HT disabled), w/2Gb of RAM running a generic
kernel, w/out IPv6 support (and with DDB/KDB included obviously)
This machine just 'hangs' every couple of days. I have DDB/KDB compiled in
- and if I throw it into DDB I get the following:

I have a crash dump from it - which I've saved (I'm moderately familiar
with working with dumps, but this one is split into two?)
If anyone has any pointers, or can do some hand holding to get more info
from the dump, or what to do next time it happens?
Cheers,
-Karl
