Re: Informix crashing UNIX on HP
I had never heard of this problem before on HP. We have been running
7.20 - 7.22
for over a year with as many as 10 x 8 Mb extents at one time (ie
during heavy load).
Unfortunately there is no messages in the message log. Unix panics and crashes
On the system console we get a
"Stored message buffer up to panic:
vuseg=810000"
and the Unix box shutdowns and restarts!!
The curious thing is that I can allocate Virtual mem using onmode -a
and release
it via onmode -F. But when I monitor the mem segments with onstat -g seg
and I see that the free blocks are almost all exhausted Informix will
at this point
cause the box to reboot.

Eeek, I haven't seen it bring OnLine down. What is the specific error?
Make sure you don't allocate more than ONE VIRT segment on an HP box.
This is normally just a performance issue, but could be your problem?
