BESServer - REQUIREMENT FAILURE in Relay.log

Hi all,
We’re getting following error logs in our BESRelay.log from the BES Root Server.

/data/property-results-of-computers (4892) - REQUIREMENT FAILURE: false (GetPropertyResults.cpp:128)
/data/property-results (7524) - REQUIREMENT FAILURE: false (GetPropertyResults.cpp:128)

In our env we are running BigFix 9.5.5. on Windows Server 2012 R2.

Someone knows these problems?

Many Thanks!

Nobody has any idea?
