Warning "Unrecognized command key" in TransferComplete message

[Oliver Kraitschy]

Hi all,

when doing file downloads on some routers, I get the warning "Unrecognized
command key" in the TransferComplete message. This has the effect that the
download task is not removed from the task queue but executed endlessly.

Has anyone experienced the same? Any ideas on what is causing this and how it
can be avoided?

Thank you in advance.

Greetings,
Oliver
