Scheulded Jobs Hosted on IIS Not Always Firing

Product: PowerShell Universal
Version: 1.5.9


First time poster here, I’ve searched around and found a few topics on this, but it seems I’ve tried most of the proposed solutions, so I’m a bit stuck.

I’m running PowerShell Universal on IIS and have two scripts that are scheduled to run, one at 6:00, and the other at 6:15am, and have noticed they don’t always run. It seems like all is well for a few days, but then they just don’t kick off and I have to manually run them. Below a screen shot of both my schedules.ps1:

I’ve also followed,, and made sure my “Idle Time-out” is set to zero.

I’m sure it’s just something simple I’m missing, but I just can’t seem to figure it out, any ideas?


I believe this is resolved in 1.5.12. I was having similar job/scheduler issues and they were resolved in this patch.
See the current changelog here: Changelog - PowerShell Universal

I’m having the same issue.

Can you make sure you’ve set the app pool settings to prevent it from stopping?

All settings are confirmed.

Ok. You’ll also want to check for app pool recycles: iis - How to Find App Pool Recycles in Event Log - Stack Overflow

If the app pool is recycling, it can cause issues with scheduling.
