In earlier versions you must use AppLog to find out which logs have problems.

b) Start->Run... afwapplogviewer
c) Click OK, accepting defaults in the two following dialog boxes
d) Select the node and Basic History (AdvHtHistorySrv) service provider emitting the error
e) Select Operations
f) Find & select the AdvHtHistorySrv(collection apartment operations) ListCollectorMap operation

The "item=" points to the object having the Log Configuration. Look it up with the Find Tool; then figure out if the log is obsolete, or can be repaired (select new valid OPC property, etc.).
