You have to run the backend using gdb, and get a backtrace of the crash,
or check the postmaster logs for any information.
No core dump that I can find. But, the logs are reporting errors from
semget in ipc.c. Specifically, it is complaining of not enough space,
but I have no full filesystems. This stuff is part of the locking
code isn't it? Did that get tweaked with the NetBSD/vax patches
recently?
Cheers,
