I think you need to take this discussion to a PowerDNS forum/mailing list. What you're saying doesn't seem possible. It's highly unlikely a query will cause a DNS server to crash because "MD5 is disabled at the O/S Level" (whatever you mean by that). However if your OS has a mangled SSL library, all bets are off.
