Mirrorbits randomly goes "redigo: nil returned"
With no evident pattern, sometimes Mirrorbits stops redirecting and returns "redigo: nil returned" in the HTTP body. Other parts seem to work fine (mirrorstats, mirrorlist, checking that mirrors are up and up to date) and the log shows nothing different. Reloading the config doesn't help, restarting the service makes it start working once again.
