Polling Engine Problems after upgrading from 9.0 SP2 to 9.1

Question

We upgraded from Orion NPM 9.0 SP2 to 9.1 on October 20th.  Ever since then the Polling Engine is having problems.  It stops every day in the middle of the night (around 2 to 4AM) We have to end up rebooting the server to get Orion polling again.  This has never happened before, only thing we did was upgrade to v9.1.  We have the APM v2.0 module installed and it does seem to be affected by this as it continues collecting data independent of the Orion NPM polling engine stopping.

OK.  Please update your support ticket with this information.

Well I upgraded APM 2.0 to SP2 but that did not fix the issue.  Every night when the nightly maintenance runs at 2:15AM, the polling engine stops and does not get restarted.  This never happened before I upgraded to Orion NPM 9.1

Thanks. I did open a support ticket. Case #65251.   I applied the APM 2.0 SP2 today so I will let you know if it fixes the problem with the Polling Engine stopping and not restarting after the nightly maintenance is run.
