Re: System lockup

Then I think it's a kernel (Red Hat kernel 2.4) bug, because I've had the same issue on 4 different machines of different ages and configurations, using the same or similar datasets and using different ones.  I wanted to eliminate postgres as a culprit because it would be the easiest thing to correct. 

As noted in my previous post I'm currently experiencing the problem on a Red Hat 8.0 and 7.2 (fully errata patched) (and am currently testing a RH7.1 install without patching the kernel to see what I get [so far no lockups {4 days production load}]). 

So, I think it's time ti switch to FreeBSD, or move my question to a Red Hat list.  I'll give the Red Hat geeks a chance to answer before becoming a trait..., I mean moving to FreeBSD.

The whole system freezes, not only Postgres?  In that case I don't think
you need to guess very hard: you've got a hardware problem.  Well, maybe
it could be a kernel bug, but I'd bet hardware.  In any case, Postgres
is an unprivileged user process: it can *not* lock up the rest of the
system.  It could tickle a kernel bug that results in a lockup, but that
doesn't make it Postgres' fault.
