>>The only other job that could be running is a vacuum I run at 1am but I don't think it would take an hour to run.
Famous last words... :-) It should be easy to check this, but I don't know if that is a likely source of problems anyway. If I were you I'd just do VACUUM ANALYSE in one comand. It would certainly eliminate that as a factor. At this stage you have no idea which table it occurs on, or if it always happens on the same table, or at the same time, am I right? Failing any more useful response from those with more internal knowledge you may have to resort to collecting information and trying to isolate the problem. It would be a good idea to give all the relevant version numbers too regards iain ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
