3750X Failed to send hrpc non blocking message

michael.hinz · ‎08-24-2013

Yesterday I upgraded one of our 3750X switch stacks (8 total switches) to version 150-2.SE4 (c3750e-universalk9-mz.150-2.SE4.bin). I noticed that after the upgrade I receive a lot of log entries of this type event:

Aug 24 08:57:04: Failed to send hrpc non blocking message

This log event was not showing prior to the upgrade. Does anybody have an idea what the cause for this message could be and/or how to track it down?

Thanks.

Thank you Reza. I did find that post before too but I am not sure if this applies to my case. I have restarted each individual switch in the stack one at a time and kept monitoring the logs. The error continued to be logged even after I rebooted every switch (and during the reboots). I also tried shutting down all the fiber uplink ports going away from the stack and it did not solve the issue.

Any other suggestions on how to track down what the source (source port?) of the problem could be?
