Hello,
after running bind-9.3.2 for several days now with
#define ISC_MEM_USE_INTERNAL_MALLOC 1
compiled in, I believe I can say my problem was not version dependent
but malloc dependent.
One of our resolvers currently handles some 10.000 queries per second at
a load of 0.5 and an average CPU usage of 15-20%.
Kind regards
