Issue/Introduction

When a remote Landscape goes down from the MLS you will have an alarm: CONNECTION TO LANDSCAPE CANNOT BE ESTABLISHED.


We have implemented the workaround as described here

However when the situation normalizes the clear event 0x10c1a arrives out of order (2 minutes early before the critical event) and the critical alarm  0c10d23 is not cleared.

Why do these events arrive late and out of order?

 

Environment

Release : 21.2.8 

Spectrum DSS environment

Cause

Timing issue in the way the events are created and received

Resolution

Patch 21.02.08.D99 has resolved the issue.

Additional Information

Engineering believes that the timing issue will be resolved in a future release of Spectrum due to the architecture changes that are constantly changing with Spectrum.  If the issue still exists after 22.2.5 Engineering will create a new patch and add the fix into Spectrum mainline.
