It is coming from a SIGTERM, but I'm not aware of any platforms that
respond to exceeding the ulimit open-files limit by SIGTERM'ing the
process. I think you're barking up the wrong tree.

I think it *would* cause a problem, unless Solaris can support unlimited
numbers of open files --- we have certainly seen PG eat all available
file table slots on other kernels. I don't recommend raising nofiles.
The backends are perfectly capable of working within the nofiles limit
you set, and 256 seems high enough to avoid thrashing.
