Symptom:
profiled devices are not being profiled on the PSN they are authenticating to.
Every minute the endpoint profile server changes.
when the profile server changes the static group assignment check box is toggled.

We can see inconsistency between endpoint static assignments and what those groups believe to have assigned to them. Meaning the endpoint is set to true but doesn't show in the group and visa-versa.

if only one PSN is enabled the issue no longer happens

if the aaa server psn and the profiler server psn are the same the issue doesn't happen. if they are off, the toggling will continue.

Conditions:
ISE 1.2 patch 6
more than 1 psn doing profiling
endpoint profiler server changes ownership between psns.
