Including an actual code snippet and the full error traceback would help a lot.

According to http://en.wikipedia.org/wiki/List_of_FTP_server_return_codes ,
error code 550 translates to:
"Requested action not taken. File unavailable (e.g., file not found,
no access)."

Does the logfile get rotated or something, thus causing it to briefly not exist?

It might also help if you explain how your logfile system works.
