From just the current logs, I would agree with Nick. The server process grows to over 1 GB (archived logs show it growing to 3.5 GB). See below [1] This would cause all new workers to inherit a huge amount of shared memory which would trigger our PSS memory threshold checks. Therefore, I'd say this is a duplicate of bug 1535720 (memory leak) and bug 1479356 (use USS instead of PSS for checking worker memory). We should ensure these two fixes are applied, the memory leak one being more crucial, and see if this still happens. We can open a new bug if this issue still happens with the core worker after both fixes are applied. What do you think Ryan?

Closing a duplicate for now. The fixes for the above BZ should resolve the problem. *** This bug has been marked as a duplicate of bug 1535720 ***
