Carfeul reading of the aforementioned file uncovers the fact that the default value for NMBCLUSTERS is (512 + MAXUSERS * 16). This means that unless you had MAXUSERS set to something below 32, setting NMBCLUSTERS to 1024 may not have had the effect you intended, since 512 + 32 * 16 = 1024. I have plenty of RAM to blow on my home -stable box, so I have MAXUSERS set to 64 and NMBCLUSTERS set to 8192. -- Noone else has a .sig like this one.
