to be more specific I need to reference my own post from Feb 15.
(Resolver (bind-9.3.2) eats processor)
I see a strange behaviour of bind-9.3.2 resolvers which has been
verified with bind-9.3.1, too.

I compiled with system malloc and "--disable-threads", occasionally the
named process uses 100% of CPU over hours answering the queries very slowly.

Currently I am testing with "ISC_MEM_USE_INTERNAL_MALLOC 1", so I still
don't know whether this change has a positive effect.

I summarized some information at

Kind regards
