System is Windows Server 2003 Standard SP1 running DNS services, fully patched and current with all Windows updates. This machine is a secondary DNS server. After being in service nearly 2 years, jsut 2 weeks ago this server suddenly began using excessivly high amounts of memory for the dns.exe process. By high, I mean that after restarting the DNS service, it begins a near-linear increase (no spikes, just fairly constant slope upward) in memory use, easily exceeding 1.25 GB of memory after 4 or 5 days. I restart the process, and the even repeats itself. Until now, memory use was nearly a flat line.
I have completely uninstalled the DNS service, and re-installed.
This machine serves only a few hundred zones (stored in zone files & registry, NOT Active Directory, is stand-alone server and not a member of any AD domain) and answers ONLY for its own zones (recursion is disabled, root hints file has been removed).
I have repeatedly googled and searched the MS KB for answers on high memory utilization for the DNS service, but have come up with noting relevant.
Anyone seen this problem, or have a reference to a known issue/fix?
