Comment 3 Vladimir Kvashin 2016-03-17 20:54:02 UTC 
This is again connected with link children.
This is also connected with massive FileDeleted events processing.
I already now at least some reasons. Fixing them, in conjunction with recent link related fixes should fix the issue.

The issue 257076 that is marked as a duplicate also contains an interesting heap dump data. But root cause is the same.
