I got this on or soon after ha core restart with core-2021.12.9:

This is likely because pending requests were not cancelled or new ones were initiated after the serial port was closed.

This happened during the startup phase and the exceptions were reported as 'Task exception was never retrieved'. I do not know if that applies to exceptions generated before startup (during the previous shutdown).

It doesn't look critical, I am mainly informing about this.

Still happening with other radio. Only at startup, 1 year old & not critical -> closing.
