PLATFORM_INFRA-5-IOS_INTR_OVER_LIMIT

Issue happens on 3850/3650 seris switches

Impact: – Switch may hung or reload once the memory exchausted

If the switch got reloaded, caputure the below output twice (8 hours or 24 hours interval)and compare the result. If the switch is not reloaded, caputure the below output twice (8 hours interval)
and compare the result.

Show clock
show platform resources
show process memory platform
show platform software status control-processor brief
show platform software process memory switch 1 r0 all sorted –> Compare this command output with the second output
show platform software process list switch active R0 sort memory –> Compare this command output with the second output

Sample output: – In the below case, it was due to CSCvh89372 and we have done the upgrade.

Acton Plan: – Upgrade the switch once the bug is identified
workaround :- reload the switch

Action Plan: –

The error message pointing to hardware related (ASIC), to confirm, Re-seat the affected module (in this case it is Module 2) and monitor

If error recur replace the module.
