Could it be that I have too much memory allocated for postgresql? My resource settings are: shared_buffers = 94952 temp_buffers = 1GB work_mem = 19339 maintenance_work_mem = 191845 max_stack_depth = 2MB I'm running on a server with 3.7GB of RAM. I will adjust the logging level and wait for another crash. Should I set the level to 'debug5'? The cluster is for development purposes, so I don't mind the overhead.

I wonder what caused that? It's not clear that'd have led to the crash though. regards, tom lane ______________________________________________________________________________________________________ This message contains information, which is confidential and may be subject to legal privilege.
