DNSCache excesive memory usage Windows Server 2008 R2
- by MikeT
We are having an issue with the dnscache service where its memory usage is becoming excessive (~6GB) after a week or two.
Restarting the service frees this memory but performing ipconfig /flushdns does not, an ipconfig /displaydns shows aprox 15-20 entries in the cache.
We have checked and there appears to be aprox 150 DNS queries per second taking place but I would not expect this to have the effect of causing this memory issue.
I have tried to search MSDN for hotfixes or bug reports but I could only find a reference to a memory leak in windows 2003. can anyone suggest how to proceed.
