We have 2 virtual NAC appliances with identical configuration (I’ve attached some info).
On busy moments, we get a lot of complaints of users not being able to log on to random laptops (using identifi wi-fi and the nac with AD/nps for auth)
so I did some digging in (many) logs and status pages of the nacs.
I noticed that on one device the “UpdateService Thread Pool” and “UpdateService Scheduled Thread Pool” builds up about 25.000 throttled tasks per day. The screenshot I’ve attached shows the state 2 hrs after a “nacctl restart” command (this seems to reset it to 0)
On the other NAC, this value is most of the time very low and doesn’t throttle..
I notice the complaints are less when the “nacctl restart” command cleared the queue, but this is no solution..
anyone has an idea?

You run the version 8.1 and the current release is 8.5.
There are so many enhancements and bug fixes released since 8.1.
The risk is to chase a known issue and to lose a lot of time in debugging.
Wouldn’t be an upgrade to 8.5 an option?
