HPM Main Process, High CPU

Good afternoon I have a 48 port 3750E switch running ios 12.2(46)SE. The switch rebooted twice this morning for no reason that we can think of. The power is fine and the room was locked. When it re-loaded we noticed the CPU usage is quite high, around 68%. Our other LAN switches run around 7-10% on average.

The culprit seems to be the HPM MAIN PROCESS, which is running at 50%. Through my digging I've been unable to find out exactly what this process is or what it could be doing to eat up this amount of CPU%.

I'm pretty sure I haven't provided enough detail so please let me know what information would be helpful in trying to determine the root cause. I've attached the running config below. Thank you

It seems like we found the root cause of the high cpu. There was a faulty fiber cable running from this switch to another floor. On the other switch the fiber cable was hanging on by a spring, it was halfway out of it's boot, just barely hanging on . My assumption given the information on what HPM MAIN PROCESS does is that the connectivity although not breaking may have been fluctuating enough to disrupt this process.

After switching the cable, and reloading the process has been normal, and this is since Monday. Thanks to everyone who assisted, I really appreciate your input and time spent!
