Issue
When Sigma is restarted the Alarm manager does not run.
Environment
Sigma release 4.04
Cause
The Alarmslog.rec file is too large.
Resolution
The archiving process in Sigma release 4.04 occasionally failed and the AlarmsLog.rec file was allowed to continue increasing in size, this file is some cases might reach 2GB, which would cause the Alarm manager to fail.
To correct this issue, carry out the following:
1 - Stop the Sigma Client and Server.
2 - Using Windows Explorer locate AlarmsLog.rec in the C:\Sigma\Data folder.
3 - Either rename or delete the AlarmsLog.rec file.
4 - Restart the Sigma Server and Client.
Note:- a new AlarmsLog.rec file will be created when a new alarm arrives at the Server.
5 - An alternative to this procedure would be to upgrade to the latest release of Sigma.
