Recursive query fails, and authoritative query back to clients with ttl 0 :( I increase memory on servers 2x QUAD CORE XEON up to 12Gb.

I'll try to test 9.7 on one of the heavy load servers and post results to you. _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
