I think I figured it out: vm.overcommit_memory = 2 vm.overcommit_ratio = 50 Only allows me to use 50% of my RAM... ugh! I have 16 GB, so when only 8 is left, I start seeing OOM. Will increase this setting and see if it helps. Thanks everyone for the help. Greig -- Sent from: http://www.postgresql-archive.org/PostgreSQL-general-f1843780.html
