This is the second time this month that the backend dies on me, and I hope someone can tell me what the reason is. I look at the log (debug level 2), and the last message is: /www/server/pgsql/bin/postmaster: reaping dead processes... /www/server/pgsql/bin/postmaster: CleanupProc: pid 22650 exited with status 0 /www/server/pgsql/bin/postmaster: ServerLoop: select failed proc_exit(1) [#0] shmem_exit(1) [#0] exit(1) It occured to me that this is not in Postgres's SELECT, but rather in select(3C). Which suggests that it has something to do with file descriptors. The question is what I have to change to prevent this from happening.
