If you're saying that the server you're concerned about is running 
9.2.x, the correct answer is, "Upgrade." It's been EOL for a long time 
now, and even if you find bugs in it no one is going to care. :)

In fact, your best bet at this point is to upgrade to at least 9.6.x, 
and preferably 9.7.1-P1 since you're going to want to take advantage of 
this opportunity to prepare for the possibility of DNSSEC.

If after upgrading you are still having problems, then we definitely 
would like to know.
