rblsmtpd/qmail-smtpd hung processes

I've run into a bit of a problem and if I don't solve it soon, I'm going to be without e-mail (and so will a lot of other people). This is a bit long, I'm trying to include anything that may help.
The problem is that qmail-smtpd and/or rblsmtpd get stuck and don't close. After a while the server just quits accepting smtp connections, or will connect/disconnect very quickly (connection closed by foreign host). Using kill on these processes just opens another instance of them (they're managed by /var/service). Since I'm not seeing any log activity that shows what's going on, I'm having a hard time figuring it out. I know the processes are supposed to be timing out and closing, but don't seem to be doing that
Has anyone seen this problem? I've tried searching for info on it, but can't find anything that looks similar. I currently have rblsmtpd disabled since it sits between the outside world and qmail-smtpd. The errors don't occur quickly, it seems to take multiple hours to occur so this is hard to debug because I can't create the problem on demand. Any ideas are welcome. (hopefully I'll be able to get mail from this address long enough to fix this - it's one of the ones that's been moved to this machine already)

A quick bit of history:
Our email/dns provider is closing up shop in about a week (good friend of mine was a small ISP). I only had about 3 weeks notice on this and I've been configuring a pair of FreeBSD machines (I posted to the list a couple weeks ago, thanks everyone for good replies, ) to take over DNS and E-Mail for about a dozen sites. Basically I've been on a crash course of learning as I go.
