Re: Falling Memory

Andrew,

I think what you're seeing is QDNS filling up its cache with answers that it's
received from other name servers. By restarting it, you're forcing it to dump
all of that cached info, which means that it has to send out new queries if it
subsequently needs any the info that had been cached. The effect is that QDNS
will be somewhat less efficient until it builds its cache back up. So, you
should allocate enough memory to QDNS for a reasonable cache (what that is
depends on what kind of use your name server gets), then leave it alone and
don't restart it unless absolutely necessary.
