Hi all.

I have some problems on one of my machines and I have recompiled kernel 
there with:

option KDB
option KDB_TRACE
option KDB_UNATTENDED
option DDB

option DEBUG_MEMGUARD
option DEBUG_REDZONE

option INVARIANTS
option INVARIANT_SUPPORT
option DIAGNOSTIC

option WITNESS
option WITNESS_SKIPSPIN

Before this ZFS can take gigs of memory (there are 64Gb RAM on the 
server) but now it only takes not more than 4Gb. Am I missing something 
in my configuration or is this the way it should work?
