Then the behavior you showed is impossible ;-) There is *something* that is completely broken about your machine, and the rest of us really don't have enough context to tell what. You haven't told us anything about the hardware or operating system, or how you built or obtained the Postgres executables. I don't think you should dismiss the possibility of a hardware problem, especially since the failures aren't 100% reproducible (AFAICT from your previous remarks). We've seen more than one case where Postgres stressed a system more than anything else that was being run, and thereby exposed hardware problems that didn't manifest otherwise. For instance, a bit of bad RAM up near the end of physical memory might not get used at all until Postgres starts eating up memory. Another line of thought is that you built Postgres with a buggy compiler and thereby got buggy executables. Have you tried running the PG regression tests? regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 1: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to majordomo@xxxxxxxxxxxxxx so that your message can get through to the mailing list cleanly
