Hi all!
How to deal with such type of error? No my code in trace, no clue what happened and where to see.

Task terminated with unhandled exception: Acquiring reader of already owned connection.

Ok, I resolve it, but it was not good time.
http://vibed.org/api/vibe.http.server/HTTPServerResponse.waitForConnectionClose
I tried to use this function to close my service threads on HTTP connection close. It was a bad idea because when this function running, you can't write to response bodyWriter. I found in documentation nothing about this exclusive usage.
