RE: DNS high memory issue

[altuntason]

Lots of 5051 and 3000 (DNS server has encountered numerous run-time events.
To determine the initial cause of these run-time events... )nothing more. 

(recursive query is enabled on server)

i have enabled the dns debugging but it's hard to analyse manually. Do you
know any good tools to anaylse DNS debug logs?

 

Thanks.

I know this is for Win2k8, but I am sure there is probably some similarities

Is there any other DNS related errors before the 7052, looks like a lot of
5051. 

 

Do you have Debug Logging turned on, is there anything in this debug log
that might trip off what could be happening. 

 

Its either that or possibly recursive queries and/or abuse thereof.

Hi. 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.
