We turned off NUMA in the BIOS on Jul 2nd and haven't seen the issue since - (though once last week, we had the connections count go up to 1000, but recovered in few seconds on its own). Will keep you all posted when I have more updates.
Appreciate everyone's help, comments and suggestions so far. Thank You. Ramya -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
