Hi,

Status is .. warning. If you have support contract open a TAC case.

Are you seeing ... 

Large number of following messages:

%PLATFORM_INFRA-5-IOS_INTR_OVER_LIMIT: IOS thread disabled interrupt for 32 msec
-Traceback= ...

In order to troubleshoot this issue a memory usage statistics need to be captured on the platform level using the below outputs:

- show platform resources
- show process memory platform

Monitoring the RSS counter helps confirm the process that is responsible for the memory leak.

May be CSCvh56835.
