My apologies if I'm posting the wrong place, or am asking a common
question. All my looking so far hasn't turned up anything very useful
in knowing what to look at, or what to modify.

CentOS 5, running BIND 9.3.6
i386
Hardware:
P4, 2.8Ghz, 1G memory
Sata drives - non mirrored etc.
Load is light, usually under 0.1
--
This box is running Postfix as our mail server. BIND (9.3.6) [Latest.]
--
Problem:
Postfix is doing RBL lookups on zen.spamhaus.org.
Everything goes along groovy - but then lookups start failing.
Early in the process, we get stuff like this: [We have a "successful"
lookup, and then a failure...]

Apr 14 14:25:05 mail postfix/smtpd[22281]: NOQUEUE: reject: RCPT from bzq-79-183-5-119.red.bezeqint.net[79.183.5.119]: 554 5.7.1 Service unavailable; Client host [79.183.5.119] blocked using zen.spamhaus.org; from=<contriveclaudia@xxxxxxxxxxxxxx> to=<contriveclaudia@xxxxxxxxxxxxxx> proto=SMTP helo=<bzq-79-183-5-119.red.bezeqint.net>
Apr 14 14:25:07 mail postfix/smtpd[22804]: warning: 33.229.242.205.zen.spamhaus.org: RBL lookup error: Host or domain name not found. Name service error for name=33.229.242.205.zen.spamhaus.org type=A: Host not found, try again
---
As you can see, we had a lookup succeed and then just right after, one fail - claiming it got no answer from BIND. I get others after this that SUCCEED - so it's not in 100% failure mode yet.
After time [how much, I don't know] eventually all the zen queries
[or most all] fail.
A bind restart fixes the problem. [Hmmm...]
---
I do some logging in bind, and I don't see any reason for them to fail. Here's a bind debug log of 5 on that failure above.

As far as I can see, the BIND query simply didn't get a response -
but no errors?
---
First, someone's going to ask - perhaps Zen's blocking you. I don't
think so. Here's why.
-We're non-commercial, using the definition set my spamhaus,
-mail connects TOTAL are well less than 100K a day. (Less than 10K in actuality)
-and thus having more than 300K queries is pretty unlikely.
-Also, let me remind you that a restart of the bind service seems to
make the failures go away for a while, so if zen were blocking our queries, I'd think that wouldn't make a difference.
---
I certainly suspect a problem with BIND, but I can't find it, and have no idea where to go from here.
I simply don't know where to look any more. If BIND were having a problem, say allocating memory, or something, shouldn't it be in a debug level 5 log?
HELP!
-Greg
[Cross posted from elsewhere, but I'm at a dead-end right now, so
looking for a steer in where to ask, or direct help! TIA]
