Performance Management releases r3.7.10 and earlier
This issue has been fixed in CA Performance Management 3.7.11.
Symptom: When a device has more than 150 interfaces the Alarms View on Alarms tab of device context page fails with error, "An unexpected error has occurred".
Resolution: Addressed issue that Alarms View on Alarms tab of device context page fails with error when a device has more than 150 interfaces.
As a workaround use Alarm based Views added to Dashboards. Set them to a Group Context via the Views configuration itself, or via the Dashboard level Context settings.
If the Alarm based Views added to a Dashboard are set to a specific Device for the Context, if that device has more than 150 interfaces it will generate the same problem. This is true whether setting the Context at the Dashboard or View Configuration level.
