Issue:

After upgrading to Spectrum 10.2.2, Spectrum will crash into a core dump with repeating IHLacpComputeThreshhold::calculateThreshold in stack.  The crash may occur immediately or after a few days.

Environment:
Spectrum 10.2.2OS: Any
Cause:

LACP Thresholds were added to Spectrum 10.2.2 for Bad Link Alarms, however due to a bug in the code it is possible that these thresholds will loop, consume all resources and crash the SpectroSERVER.

 

The amount of time before the crash depends on available resources and how many interfaces are modeled with LACP.

Resolution:

Please request patch 10.02.02.D276 from Support.  

Additional Information:

Problem is only seen in Spectrum 10.2.2.
