zero page reclaim causes high DA utilization?

Folks, I recently began reclaim on all SG's within a VMAX 20K and shortly thereafter (maybe a couple hours) SMAS began alerting us that DA's at 90% utilization. I have been trying to trace it down to a particularly heavy hitting SG but then realized this could be CPU utilization on the DA. Incidentally, when I examine Port Utilization on the same DA's, both ports 0,1 are about 20% utilized. The method I used is below. Any thoughts as to my being on the right track or other ideas? Appreciated!

symconfigure -sid xx -cmd "start reclaim on tdev in SG SG_NAME;" commit -nop
