Peter Walsh commented on TS-2299:
---------------------------------
We are seeing this with 4.1.2 as well. We have noticed a pattern in that this
happens shortly after a node joins the cluster.
We attempted to build ATS with debug to get more info, but the method
TSContScheduleEvery generates asserts with debug on. We'll have to remove that
assert and try again, but in the mean time I will file a separate bug for that.
