The others show minimal usage. Consuming all of one CPU is quite normal if a query requires a lot of CPU-intensive work such as some types of text processing, calculations, etc. I have quite a few CPU-bound queries in the system I'm working with, and they cause no problems. > I would think that other users would get a different core and one query > could not deadlock the whole system for everyone. That should indeed be the case. Are your other users completely unable to run queries, or are they just too slow? Have you tested by connecting with `psql' and running queries by hand? Have you checked the pg_locks table to see if there's any possible locking issue preventing the other users from proceeding with their queries? Is your disk subsystem also working hard during these difficult queries? -- Craig Ringer -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
