3750 stack - high cpu for "hulc running con" every one or two minutes

Question

I have a stack of 4 x 3750 :
Switch Ports Model              SW Version            SW Image
*    1 28    WS-C3750G-24PS     12.2(53)SE            C3750-IPSERVICES-M
     2 12    WS-C3750G-12S      12.2(53)SE            C3750-IPSERVICES-M
     3 12    WS-C3750G-12S      12.2(53)SE            C3750-IPSERVICES-M
     4 28    WS-C3750G-24PS     12.2(53)SE            C3750-IPSERVICES-M
And every minutes or two minutes (approximately), I have high cpu for "hulc running con" without doing anything.

How can I find which is doing a "show run" ? Which debug can I do ?
Thanks

Answer 1

We solved our problem it was caused because we were routing in and out the same L3 interface.
Fixed this issue and our CPU dropped dramatically.
