We've seen this issue for the last 3-4 weeks and have not been able to find a resolution.
We're an enterprise of just under 10k assets, we are using an IP scan of all subnets on our network. This has been working until recently when the devices stopped processing out of the scanning queue and the scanning queue continues to build up.
We're able to get 6-12 devices to scan through after restarting the Lansweeper Service, but then the queue goes back to stalling and building up.
We've added a second scanning server and have found that to perform the same way.
Currently I've disabled all scheduled scans and are trying to process scans manually, but see the same issues?
This has been submitted to support 2 days again, heard nothing back, hoping community may have ideas for us to try.
