Errors like "ps invoked oom-killer" were seen in /var/log/messages. This started happening in the 8.2.6 release and is fixed in the 8.2.7 release as well as nsr-2 for 8.2.6.
Release : 8.2.6-55530
This is the only release where the problem is seen.
There was a bug in the tonicd process which processes files for providers.
NSR-2 for 8.2.6 fixes the problem. It is available here: https://license.soleranetworks.com/upgrades/NSR826-2
