Windows error logs
Last modified: 2017-08-21 16:17:34 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.
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
