Thread: Postgres crashes on cygserver

Postgres crashes on cygserver

From
David Mitchell
Date:
I've built postgres to run on cygserver rather than cygipc because we
were experiencing hangs that had previously been thought to be caused by
cygipc. After building postgres it worked fine under heavy load on my
workstation, and both our development machines. However, once deployed
to our production server the problem reappeared.

What can I do to alleviate this problem?

Whoops, turns out it doesn't work on both development machines, only one
of them. And the production machine and development machine that doesn't
work have this in common: they are both multiprocessors (two
hyperthreaded processors to be precise, so windows sees 4 cpus).

I tried setting the cygserver process to have an affinity for only one
cpu but the problem still arose.

Are you using the latest version of Cygwin?  If not, then upgrade and
try again.  If so, then please report this problem to the Cygwin list.

Thanks,
Jason
