Alert for event Id: 56724 ('UDC_AGENT_E_EXCEPTION_CALLBACK')

Microsoft.LS.2015.Monitoring.Rule.InfoEvent.Registrar.UDC_AGENT_E_EXCEPTION_CALLBACK (Rule)

Knowledge Base article:

Summary

An unexpected error occurred during while the Data Collection API was executing a callback.

Causes

The Data Collection API receives data from other Skype for Business Server components asynchronously. After the data is captured, a callback is executed to allow the components to process the result of the data capture. This callback threw an unhandled exception and must be investigated. Other events in the event log will likely point to the reason for this error.

Resolutions

No action is required by the administrator because the Data Collection API protects itself from unhandled exceptions during callbacks. However, the root cause of this error should be investigated and fixed to avoid this from happening in the future.
