Best thing to do is: - Make sure your postgres is compiled with debug info, either in the binary or split out. - Enable core dumps prior to starting the postmaster. "ulimit -S -c unlimited" should do it. When it crashes next you should get a core file in the data directory. Run: gdb /path/to/postmaster /path/to/corefile Type: bt and post the result. That should pin-point it. Have a nice day, -- Martijn van Oosterhout <kleptog@xxxxxxxxx> http://svana.org/kleptog/ > From each according to his ability. To each according to his ability to litigate.
