Jobs changing from Running to Queued after upgrading to 8.1

Hi All,

We have been running 8.0 for some time now with no issue in our imaging job.

We recently upgraded to 8.1 and ever since that, when running our imaging job to a batch of computers, at some point the job status will change from running to queued.

What really happens is the jobs even though they are saying queued actually restart. If they were past the imaging stage and were onto the configuration stage, they'll reboot into PXE and do all the tasks again.

The status will always say queued at that point until the job gets through all the tasks then it will change to completed.

Any ideas on what might be changing the status from running to queued and restarting the job?
