Good evening!

My c3750 switchs cpu utilization is 100%. In the cpu proccess list I see a proccess named Background waiting and it consumes 92%.

Can anyone tell me please what proccess is it and what is it responsible for?

There is a new IOS (12.2.44-SE2 (ED)) try to upgrade the IOS. We had a problem with SXH2a on a 6500 with high CPU and reboots. The IOS upgrade solved it.

I was going to upgrade it, just wanted to know if upgrading is the only option in this case. Thank you anyway

The issue is still there. I have upgraded the IOS, but CPU utilization is stil 100% due to some Background process..

Desperately need help ))

I suggest opening a TAC.

Most likely a hardware issue - I think the box will need to be replaced. Open a TAC case.

Same here!
