All Postgres processes show BIND in top. Odd. I wonder if you are seeing some variant of the old context swap storm problem. The "99.8% system time" reading is suggestive but hardly conclusive. Does top's report of context swap rate go to the moon? It would be interesting to strace a few of the server processes while one of these events is happening, too. regards, tom lane -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
