The following error is showing up in the Application Director of the ENS:
ERROR (09:45:06 26-Jul-11 EDT)(alarm) Cannot write alarm.
TAC I/A Series
G3 (Niagara) ENS
The number of alarms in the system have exceeded the capacity defined in the AlarmService.
By default the “capacity” for the AlarmService is set to 500. Increasing this to a value greater than the number of alarms in the system will correct the error, however consider doing periodic Alarm Db Maintenance to keep the number of alarms at a manageable level.
