Mobility Job Setup Timeout

Hello-

We have a local two-engine VPlex installation that is starting to get busier as the weeks pass since we started migrating to it back in March.  As time moves forward, we have began to experience gui issues when setting up Device Mobility jobs.

More specifically, what we see is the 'loading' menu popup, but not always at the same time.  Sometimes it hangs when first clicking on 'Mobility Central', sometimes it hangs on the different pages that comprise device selection during job setup.

I've have spotty success fixing the situation by restarting the gui interface from the command line. 

Is anyone else dealing with this?
