We're having an issue with our MS Server 2003 DNS servers. Sometimes, dns.exe uses too much memory and starts not answering queries. When i realize the DNS service failure, i logon to the server and see that dns.exe uses ~1.5GB memory, then i kill the process. Here is the event log: (also lots of event id 5501 records) Here is the event log: Event Type: Error Event Source: DNS Event ID: 7502 Description: The DNS server was unable to service a client request due a shortage of available memory. Close any applications not in use or reboot the computer to free memory. Our DNS is open to recursive queries and use forwarders. 2gb memory is placed on server and we've been using these DNS servers for 2 years without problem. i've search google for memory leak problems but found nothing useful. Any ideas? Thanks. ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~
