High CPU Utilization in Catalyst 3750 Stacked Switch

Louisypopo · ‎11-18-2014

Hi everyone,

I'm struggling with the high CPU utilization of my Catalyst 3750 Stacked Switch. Here is the result from some commands:

I have been searching on google but it doesn't help me much.

Could you please tell me what process "VMATM Callback" and "HRPC hlfm request" do? How should I deal with these issues?

Thank you so much.

What is the exact IOS version your switch is running?

How many switches in a stack?

Louisypopo · ‎11-18-2014

Dear brother,

Here is the iOS version of the switch:

Please help me.

VMATM Callback

Sounds like you've got memory allocation error.

Can you try upgrading your stack to 12.2(55)SE9?

Louisypopo · ‎11-23-2014

Thanks for your recommendation.

I will feedback later once I try this.

InayathUlla Sharieff · ‎11-23-2014

This 'VMATM' process mainly takes care of the removing the
addresses learnt on an interface when the interface goes down.

The HRPC process apparently handles remote procedure calls on a 3750 stack

What is that you are seeing in the logs?

Louisypopo · ‎01-07-2015

Dear Sharieff,

We are currently seeing no odd logs in the log buffer of the stack, just something like these belowed.
