Timeouts when using icontrol

Hi,

 

We're seeing timeouts with our code when using icontrol. Usually the calls complete within 1-2 seconds but intermittently calls can take up to 90 seconds. We're currently running on 12.1.2 with i4800s which are brand new. We don't have this problem with our 4200s running on 11.5.1.

 

Has anyone else seen this issue?
