Hello.
We have a couple of 3750 switch stacks that have been sustaining cpu of 99%. They've been this way for more than 24 hours, and not sure what is causing the issue. We tried doing a reload of the switch this morning but the cpu came right back up to 99% after the reload. Here is the sh proc cpu:
