I'm not sure which values you're looking at in "free", but you generally want there to be very little free memory--you want the memory to be used for caching the disk. As long as the cached data isn't "dirty" (i.e. unwritten data) then it can be released very quickly and made available for whatever is needed, or better serve as a useful cache. Rebooting normally just hides other issues. -- Sam http://samason.me.uk/ -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
