We recently configured a stack of four 48 port 3750-x switches . We are noticing high CPU usage. "Hulc LED process" seems pretty high.
This has coincided with VMware servers getting slow and non-responsive at times, perhaps a coincidence, not sure.
Below I provided some outputs that might help to diagnose it
Thanks
John
