NMBCLUSTERS=3D16384 is my default kernel setting on all machines. it is also my proposition to get this into the default kernel. larger values like 256k would make the box slower i think. jordan: would 16384 make sense or would it kill machines with low mem? /k --=20 > Hackers do it with all sorts of characters.
