I think I'm starting to get a better understanding of problem. It looks like one of the threads is trying to insert a pathological (~1,800,000) number of records in one transaction in a table while the other threads are also reading from and writing to that table. I'll try to get something simple to reproduce this behavior. ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
