Hello, I have found this problem running Postgre 7.0.2. I am running pg as DB server on one internet portal, so I need to solve this problem really fast. I intend to find problem in Linux kernel (because of reported problems with VMM allocating shared memory), but I would like to ask here, if some has some similar experience and maybe some solution... This messages (still repeating) I received from backend after trying to restart postmaster... : DEBUG: Data Base System is starting up at Wed Oct 4 18:30:42 2000 DEBUG: Data Base System was interrupted being in production at Wed Oct 4 18:30:40 2000 DEBUG: Data Base System is in production state at Wed Oct 4 18:30:42 2000 TRAP: Failed Assertion("!(metaopaque->btpo_flags & (1 << 3)):", File: "nbtpage.c", Line: 181)!(metaopaque->btpo_flags & (1 << 3)) (0) [File or directory not found] Server process (pid 22129) exited with status 134 at Wed Oct 4 18:30:44 thanx much, peter ps: sorry for my english... please reply to my priv. address (this one I write from), I didn't found any suggestiuon, how to subsribe these lists.
