I just loaded up the BIND 9.5.1 port on FreeBSD 7.0 AMD64 with threads. I don't see the prominent memory leak present on my system any longer. I lost track of this thread and think two different changes might have been made, however. One via the port and one in BIND itself, so I don't know which fix is actually in effect here, but the results seem good so far. Maybe Doug and Jinmei and comment on their respective changes just for the record. -Vinny _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
