Thank you all for the replies. Overcommit is indeed disabled - the
reason we disabled it is that this very same process caused the Linux
oom-killer to kill processes. This was perhaps two months ago. The
setting was changed to, and is currently set to: vm.overcommit_memory=2
...All has been well until recently. I will research overcommit
further.
Tom, below is the information you requested.
Thank you,
Mark
