Resolver issue - drop in qps and memory leak

2011-04-08 Thread Dennis Perisa
Hi all, We are running a couple of resolvers using BIND 9.6.2-p2 on FreeBSD 7.1 and are peaking at 10,000 queries per second (qps). Recently, the qps on one resolver dropped dramatically to 3000 during the peak period. The secondary picked up the additional queries and we had a few complaints

A beginners question regarding a caching-only name server

I am new to using BIND and thought that I would start by setting up a caching-only name server on a VM running CentOS 5.5. While in this mode, my understanding is that named should be passively listening for any DNS requests that are resolved and be adding them to its local DB. Adding localhost

Hi Dennis, There are some fixes for cache management issues on recursive servers that have been released recently. This sounds like it might have been one of those problems. If you want to stay on 9.6, then I'd recommend 9.6-ESV-R4 to you Otherwise you might like to take a look at 9.7.3. Cathy
