Which antivirus? It's quite possible that this is the reason. As the files grow, the AV may take longer to do whatever crap it's doing to them, thus exceeding timeouts. In general, you can get all sorts of strange things when you run AV on your database server. The general recommendation is never to do that if you want things to work, and it will be the first thing you're told to remove. It would be good if you could at least temporarily remove it and see if it fixes the issue. >> It would also be interesting to know if there are actually any other >> processes running at this time. >> > > Yes, there were about 30 active sessions executing functions. Right, but are the processes still active at the moment whrere it crashes, or has the postmaster managed to kill them off for the restart? //Magnus
