Thanks Tom. I don't know what change I've made that the server seems to like, but it ran all weekend with no problems. But I've definitely got some new things to consider if/when it starts having this problem again.

I've never seen or heard of a case of PG shutting down "by itself". You should be looking for outside causes. What else is running on that system? If there is absolutely nothing in the server log file mentioning a shutdown, I would tend to think that something has kill -9'd the postmaster process. This has been known to happen on short-of-memory Linux systems, if you don't disable memory overcommit (google "OOM kill" for details). Whether that's it or not, the kernel syslog file would be a good first stop to check for clues. Oh, another line of thought: maybe you are launching the postmaster under restrictive ulimit settings that kill it after not very much runtime? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org/
