Aupair.exe
In the Cisco CallManager 4.x cluster, aupair.exe causes high CPU utilization on the Cisco
CallManager subscriber server. The Cisco Database Layer Monitor service (aupair.exe) monitors aspects of the database layer as well as CDRs. The database layer comprises a set of dynamic link libraries (DLLs) that provides a common access point for applications that need to access the database to add, retrieve, and change data.
Solution
Complete these steps in order to resolve this issue:
-
Restart the CDR Insert service on the publisher.
-
Restart the Database Layer Monitor service and the RIS Collector service on both the publisher and subscriber.
-
Use DBLHelper to reestablish a broken Cisco CallManager Cluster SQL Subscription.
