Issue/Introduction

End User are receiving alert even when server are set in Maintenance mode under UIM. 

Environment

UIM : 20.3.3

NAS 9.32

MM 20.31

Cause

subscr_block_size = 100 it means when this key is configured, nas will process the alarms in bulk.. but it will not check if the device is in maintenance or not and that is why the alarms were getting generated.

Resolution

 Removed the subscr_block_size = 100 from nas.cfg and restart the NAS.
