BIND Issues on High Traffic Caches

ISC has issued a statement about the performance issues that many BIND administrators are seeing.

Evidently, the new security updates to BIND are causing problems in high traffic recursive environments (more than 10k queries/sec).  Specifically, the issue exists with BIND 9.5.0-P1.  Their statement recommends that systems affected by this be immediately downgraded to BIND 9.4.2-P1, which does not exhibit the problem.

There is speculation that this is the reason that Apple has delayed providing an update for Mac OS X Server.  It’s been three weeks since the exploit was first announced and Apple has been noticably quiet among the companies publishing security updates.
