PowerShell Script Hanging
Hello,
I put together a script that works fine, it's setup as a scheduled task but after X amount of runs it will randomly hang. Once the hanging starts, it continues until I reboot the server. I cannot figure out why. I can take the same script and run it on another PC and it works without any issue but will eventually hang the same way. I can't tell if its a bug with WinSCP, PowerShell, or the script. I feel like if the previous sessions aren't being disposed correctly or something? To be honest I have no clue. It just hangs in the task scheduler or if I run it manually.
Here is the part of the log that the script just get's stuck.
The task errors with
Task Scheduler did not launch task "\Script" because instance "{654b6dbf-fd19-4a8c-8ce5-7b42590d11e6}" of the same task is already running.
Here is the script, I removed any identifying info
