I have committed changes that I believe fix this problem: http://archives.postgresql.org/pgsql-committers/2005-08/msg00213.php But it needs more testing. Would you update to CVS tip and see if you still see the failure?
It seems, patch works correctly. My tests is passed with approximatly 1e8 SQL statements without any failure. Tests runs on two boxes: PIII/1133MHz adn Quad Xeon/500MHz and works with four threads.
Further I'm going to increase concurrency up to 12 parallel threads. PS GiST passed this tests too. -- Teodor Sigaev E-mail: [EMAIL PROTECTED] WWW: http://www.sigaev.ru/ ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
