Description Christopher Ng 2017-08-14 08:43:22 CEST
Periodically unbound will spam 5-15 of these into the Windows admin logs (as seen in the Event Viewer):

[C:\Program Files\Unbound\unbound.exe:0] error: can't ioctlsocket FIONBIO off: Invalid argument.

This is on Windows 10 1703.

Hi Christopher,

Thank you for the report, I have removed it from reporting this error.  Likely it was a spurious error, while unbound is retrying to make buffer space.  On high verbosity it still reports the error (verbosity 4 and higher).

Thanks for the report!

Best regards, Wouter
