High CPU Utilization Observed on ICX7550-24F

[Elnoor]

We've noticed a very strange behavior in our ICX7550-24F . We got a very high CPU usage but didn't find anything that justify it.

That's a fascinating and frustrating issue with your ICX7550-24F! High CPU usage without a clear culprit can be a real headache. Have you considered looking into any recent firmware updates or changes in your network's traffic patterns? Sometimes, even seemingly minor shifts can expose underlying inefficiencies. It reminds me a bit of trying to understand the physics of a perfect Drift Hunters run – sometimes the most subtle variables have the biggest impact! Hope you get to the bottom of it soon.
