Any ideas anyone ? The only thing you should do with datasize is raise it. The option is there so that the process can get *more* than the default memory allocation. If you want to restict the amount of memory being used then max-cache-size is what should be set. Note for this to be effective it needs to trigger *before* named's memory usage hits the datasize limit. Lowering both datasize and max-cache-size is generally counter productive. > Cheers, > > Mark > > On 18/11/2004, at 1:09 PM, Doug White wrote: > > > On Fri, 12 Nov 2004, Michael Riexinger wrote: > > > > > >> i have freebsd 5.3-release with the base bind 9.3 (chrooted).
