Description (partial)

Symptom 1:
The output of command <i>show logging onboard misc</i> includes the following type of message:

  str_services_main:315:SSE cmd = 34 failed. rc = -22[ffffffeaH]->  EINVAL

Symptom 2:
A module may reload with the following type of syslog message:

  %MODULE-2-MOD_NOT_ALIVE: Module 1 not responding...resetting

The show system reset-reason module of the affected module may contain the following log:

      Service: Line card manager

Both issues only affect NX-OS releases 6.2(7), 6.2(9), 6.2(9a) and 6.2(11) and only apply to DS-X9112, DS-X9124 and DS-X9148 switching modules.

The EINVAL messages are more prevalent when port monitor policies are enabled. They are also triggered by external SNMP queries of module FEC counters.

The module reload issue rarely occurs.
