[PowerShell] Ping multiple servers simultaneously with PowerShell: Test-ConnectionAsync (strange problems)

Question

I am hoping the author of the script "Ping multiple servers simultaneously with PowerShell: Test-ConnectionAsync" can help me.
I found it at: https://gallery.technet.microsoft.com/scriptcenter/Multithreaded-PowerShell-0bc3f59b
I am using the version dated: 5/8/2014
I extraced the entire function from the .psm1 file for use in a script that continuously pings about 100 devices and sends an email when a device has failed three times in a row.  At some point, usually between 15 minutes and several hours, the script
stops running.  If I break out of it <CTRL>-C, and run a "Get-Job" command, I can see that a job is "stuck" at the "Running" state.  I can even retrieve the data using "Receive-Job" and it looks fine.
 Here is a sample of the Get-Job after the program froze (I changed the Source and Destination to protect the names/IPs)...
PS C:\Program Files\ServerScripts\DeviceMonitor> Get-Job
Id     Name            PSJobTypeName   State         HasMoreData     Location             Command
145678 Job145678       WmiJob          Running       True            .                    Test-Connection
PS C:\Program Files\ServerScripts\DeviceMonitor> Receive-Job 145678
Source        Destination     IPV4Address      IPV6Address                              Bytes    Time(ms)
SERVER1  XX.XXX.XXX.XX   XX.XXX.XXX.XX                                             32       5
SERVER1  XX.XXX.XXX.XX   XX.XXX.XXX.XX                                             32       5
SERVER1  XX.XXX.XXX.XX   XX.XXX.XXX.XX                                             32       5
SERVER1  XX.XXX.XXX.XX   XX.XXX.XXX.XX                                             32       5
PS C:\Program Files\ServerScripts\DeviceMonitor> Get-Job
Id     Name            PSJobTypeName   State         HasMoreData     Location             Command
145678 Job145678       WmiJob          Running       False           .                    Test-Connection
I tried added some additional output in the function to troubleshoot but I can't seem to find the root cause.  I would be happy if I could remove the "stuck" job after a certain amount time, even though this doesn't get to the root of the
problem.
Any assistance would be appreciated.  Even if you could point me in the right direction.
Thank you.

Hi,
Questions for Gallery items should be asked on the QandA tab of the listing, as that is usually the fastest way to contact the script's author:
