Hi all; we have a client experiencing the following scenario: - Postgresql 8.3.10 plus postgis 1.5.1 - Both databases stop responding to queries and several of the backend processes show as being in an uninterruptible state (state "Us" according to a ps aux) - The client killed the processes, did a pg_dumpall and a restore only to find the condition happen again the next day - The client read every file reported by lsof as being accessed by a backend process without issues.. thus it seems to NOT be a disk I/O issue.
