Yeah - I have numbers that updated before the stats collector started freezing. Do you know which version of PG this started with? I have upgraded 8.1.3, 8.1.4, 8.2, and 8.2.1 in the past months and I didn't have the collector enabled until 8.2.1 - so I'm not sure how long this has been a problem. I might try rolling back to a previous version - it's either that or setup a scheduled vacuum analyze until we figure out this problem. I'm having to manually run it every day now... =) I think this is a pretty critical problem since it cripples autovacuum on Windows. Are you guys in a position to debug the collector process and see where it is freezing (ala Tom's earlier comment)? Anything I can do to help debug this problem faster? ---------------------------(end of broadcast)--------------------------- TIP 5: don't forget to increase your free space map settings
