MSE Losing NMSP Connection to Wireless Controllers

[Ryan Curry]

Hi all, I've just recently upgraded to Prime 3.0 and think I may have either introduced an issue or am seeing an issue come to light because of it.  I'm running a HA pair of virtual MSE (7.6.120.0) and have found that about every hour, the MSE drops the NMSP connection to my wireless controllers (all 25 at the same time).  I've found that I can go into Synchronization Services, check a controller to synchronize it, remove the CAS check, sync, add the CAS check, sync, and all is good.  I've tried lowering the Mobility Synchronization (was 60, now 30) and that hasn't helped either.  Has anyone else seen this or am I a lucky one running into a 3.0 bug?

Thanks In Advance!

CMX 10.2.x is out there, so suggest to upgrade your MSE platform to this and then there is no dependency on Prime  for location analytic.

If you want to stick with MSE 7.6.x then best to reach TAC & see if this is a known issue.

I forgot to update this, but we found the issue was tied to a previous version of Prime that was used to transition to 3.0 still running.  It appears that the server was essentially polling the controllers and causing the black out.  Once we turned off that server all was calm again.
