3750X stacks high CPU no offending process

Hi we are seeing this issue across the board on our 3750 stacks.you can see nothing showing that would cause the CPU spike.  Currently running Version 15.0(2)SE2, and have had no problems since install (march of this year). 

Not trying to upgrade/downgrade or reboot 9 stacks of 9 switches each so wondering if anyone can point me in the right direction?

See a bunch of these in the logs as well:

Currently running Version 15.0(2)SE2, and have had no problems since install (march of this year).

Use 15.0(2)SE4.

Broadcast traffic on management vlan form environment monitoring device caused the CPU pegging.

Good thing we have management traffic seperated!
