Data collector set stops, although it shouldn't

Hi
I have servers with Windows 2012R2 where configured the collecting performance counters to the SQL database.
On some severs data collector set periodically stopes collecting data. Other servers continue to collect them.
I checked event viewer - no exceptions.
Configurations of data collector sets and performance counters are identical.

I checked properties of the schedulled task in Windows\PLA\[CollectorSetName].
On servers where collecting sometime stops history property ends this rows:

Information25.06.2016 22:23:33201Action completed(2)286db1e8-67ab-4cd9-8b72-cda125fd7685

This is unnormal, coz data collector set has no stop confition. 

I can't understand why it happends.

Hope for your help.
