High Interrupts on 3750G Stack

[naeschlimann]

Hello everyone,

this is my first post in the Cisco Forum and I really need your help.

We have a stack of 2x 3750G-48TS (12.2(55)SE11)

We use this stack as a Layer 3. We have some RPA, ESX, and Storage stuff behind it.

The replications are causing high interrupt and high cpu load and they failed and this add latency in the network. As soon as we stop the replications, the cpu is back to normal.

I cannot figure out the issue. I already tried to follow the Cisco guide but I was not able to find the root cause.

If you need any informations, ask me.

Thank you

Hello

I noticed you have a ED ios installed which isnt stated in the known fixed releases which are all MD ios, This possible suggests a downgrade to a more stable MD release (12.2(55)SE9)

Does the logging report anythng?
