cache warning

Hi all !

Could someone explain to me what mean theses warnings that I find in my
cache.log file :

> 1999/05/20 10:41:19| WARNING: All dnsserver processes are busy.
> 1999/05/20 10:41:19| WARNING: 20 pending requests queued
> 1999/05/20 10:41:19| Consider increasing the number of dnsserver processes in yo
> ur config file.
> 1999/05/20 10:41:49| WARNING: Disk space over limit: 109152 KB > 102400 KB
>

I guess that I have to increase the number of my dnsserver processes (I
have 5 !) but how to choose the correct one ?

What about the disk space over limit ?

Thanks in advance,

Paul-Emile
