Thanks Martin,
However this is a database dedicated server and
nothing much else is running on it. Also, I never saw this happening with 9.2 –

I would suggest that the OOM killer is working as intended and something is not quite right within the config. You may want to review the memory consumption at peak times taking into consideration anything else running on the machine. ============================================= Romax Technology Limited A limited company registered in England and Wales.
