Sorry that you all experienced this. I wasn't able to get concurrent queue accesses even with -c 8, so I spent about half a day last week investigating a possible spinlock locking flaw. That meant the code in that area was untested, which is most obvious now. I guess that means I should test on different hardware in future. -- Simon Riggs http://www.2ndQuadrant.com/books/ PostgreSQL Development, 24x7 Support, Training and Services -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
