Yeah, I had a sneaking suspicion that shared_buffers wasn't causing the issue really. Sounds like either a hardware fault, or a BSD bug. I'd check the BSD mailing lists for mention of said bug, and see if you can grab a spare drive and install the last stable version of FreeBSD 4.x and if that fixes the problem. If you decide to try linux, avoid the 2.6 kernel, it's still got issues... 2.4 is pretty stable. I really doubt it's a problem in postgresql itself though. ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
