[Unbound-users] Resource temporarily unavailable and query problem with unbound

[Sebastian Nickel]

Hello Wouter,
> Are you out of socket-buffers?
thank you for your answer. I will try to increase the so-rcvbuf on the
system. The system is really heavy in use, so this could be a cause for
those lines.

It's a pity that there is still software which returns malformed
packets. But now I know that it is not unbound's fault.

Thank you...

Best regards,
Sebastian
