[Unbound-users] looping module stopped

Hi Gareth,

This error means that a module was activated 1000 times (or so), which
is impossible or unusual, and should not happen.  The query got
SERVFAIL, and it prints this log message.

This should not be happening, usually, lookups fail much earlier.
My quick try says that the name is an NXDOMAIN.  And works fine for me.
 So SERVFAIL instead of NXDOMAIN is no great loss (for the users), the
failsafe activated and nothing bad happened.

So, the question is why is it looping (the state machine is activated
too often)?

I would like to see a high verbosity trace of a resolution of this name
when it says it is looping; what is that module doing?

Best regards,
   Wouter
