Can EVENT ID 8270 cause Exchange Cluster to Failover?

We received the following SCOM Alert this morning:
Alert: Exchange Information Store Instance Exchange Cluster Name): The IsAlive check for this resource failed.

Checked CluADmin on Exchange Cluster and noticed that resources were failing over to 2nd node.

Obviously here is the error message for Event ID 8270:
LDAP returned the error [14] Attribute Or Value Exists when importing the transaction
dn: <GUID=1476C15A124C0C4889321F2783F32128>

that error is regarding RUS ..... RUS is trying to stamp receipint polies to the object. may be newly created object or modified object. that error is very much related with RUS and should cause cluster to failover.

Since there are errors regarding RUS please find if there are error events regarding system attendant which can cause cluster to failover...not the above error
