When one of above jobs is running, there's a small probability that will hang when PowerShell connections broken, the phenomenon as below:

1. When viewing the job status, the client has not updated the job with any new job summary and detail for a long time when job is running, e.g.
   
2. When reviewing the UC.Analytics.Insights.DataEngine.Service.log, the server has not updated the job with any new log data for a long time . 

Old versions of PowerShell are not robust enough and can cause the interface to hang in some cases. Microsoft has fixed this issue in the the later versions of PowerShell. Please review this Microsoft blog for more details.

For Example:

If the BuildVersion result is below 6.3.9600.18144, then upgrading the latest version of PowerShell can help correct this issue.
