External resolution timeouts

Hey everybody!

I'm having weird timeout issues when resolving names for which my local
nameserver is not authoritative. If I try to resolve an external name using dig
or nslookup, my query will almost always fail the first time. However, it will
succeed either on the first or second successive try.

Debugging output on tracelevel 3 shows lots of:

resquery 0x810fb90 (fctx 0x80fb378): send
resquery 0x810fb90 (fctx 0x80fb378): sent
resquery 0x810fb90 (fctx 0x80fb378): senddone
fctx 0x80f0e90: timeout
fctx 0x80f0e90: try
fctx 0x80f0e90: query
resquery 0x810fe08 (fctx 0x80f0e90): send
resquery 0x810fe08 (fctx 0x80f0e90): sent
resquery 0x810fe08 (fctx 0x80f0e90): senddone
fctx 0x80eb8d8: timeout
fctx 0x80eb8d8: try
fctx 0x80eb8d8: query
resquery 0x8110080 (fctx 0x80eb8d8): send
fctx 0x80eb8d8: too many timeouts, disabling EDNS0
resquery 0x8110080 (fctx 0x80eb8d8): sent
fctx 0x80edb70: timeout

I'm running BIND 9.2.2rc1 on Linux 2.4.20. Any ideas, hints, or nudges in the
right direction would be appreciated. Thanks!
