About 25% of the time while running my nightly maintenance script, which deletes and the copies in a large amount of new data, then vacuums and recreates indexes, the vacuum command will hang. When I wake up in the morning, everything is hosed and I have 6000 complaint emails. boohoo. :) This behavior started a few weeks ago when I upgraded from 7.0 to 7.1.3. Looking at the process list (ps -x on Readhat Linux 6.2) shows the following, 4168 ? S 1:11 postgres: postgres ucc 207.132.206.57 idle in transaction 5754 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5755 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5756 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5757 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5758 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5759 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5791 ? S 0:01 postgres: postgres ucc 207.132.206.57 VACUUM waiting 5794 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5796 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5797 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5798 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5799 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5800 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5801 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5802 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting 5803 ? S 0:00 postgres: postgres ucc 207.132.206.65 idle waiting etc... If I kill pid 4168, the idle in transaction process, then the vacuum and all the other waiting processes will proceed fine. Any clues to what could be hanging or how I could get more information from postmaster about what transaction is hanging? Thanks, Rich
