Are the timed out queries recursive or authoritative? I'd suggest tcpdump running on both the BIND servers and the client, so you can match send/receive and show missed packets directly.

Intalled package on my system is the latest bind-9.3.6-4.P1.el5_4.2 from Red Hat. My problem is that sometimes, queries are failed with timeouts and that the one of my 2 DNS servers (the one set as primaryin my users) has 3 time more failed queries than the secondary, while the succesful queries are almost the same. . I am almost sure that the problem is network related (hardware or software), but I need a proof for that. Is there any way to log the timed-out queries in a log file?
