Post media scan task gets cancelled

[HawkXP71 131]

My plugin has a task that is executed after a media scan, the task is derived from ILibraryPostScanTask andit works fine, most of the time.

It checks if any analysis needs to be performed, and if not, doesnt perform them.

However if the analysis is necessary, it can take a minute or two.

Sometimes, while its running in the post media scan, I will see in the log the following:
2026-10-09 11:14:38.504 Info TaskManager: Attempting to cancel Scheduled Task Scan media library
2026-10-09 11:14:38.504 Info TaskManager: Queueing task RefreshMediaLibraryTask

The task running (from my plugin) will finish, then any others are blocked from running.
Then another scan is kicked off.

Typically All goes well the second run of the scan media.

Any thoughts?

If a new library scan is started while one is running, then the current scan is cancelled.

How are "post scan" tasks cancelled?  It looks like it simply blocks any from continuing.

I dont know if it is possible, but it would be great if the CancelToken could be triggered.

Is there any way to delay or make the delay longer?  meaning allow the scan to continue ?

What delay? Just don’t start another scan.

I am not kicking off the scan, something in the system is.

Is there any "switch" (I have tried debug logging to no avail) that reports to the log "why" a scan has been kicked off?

Not sure why, but even without my plugins "extra work" Im noticing a bunch of "canceled scan", then the "attempting to cancel" and finally a restart of the scan.

But there is no information given (did the smart watched library kick it off, or did I click a button or something)?

TIA
