You talk about NSFBUFS? Anyway, NMBCLUSTERS and NSFBUFS maybe set at boot-time. Remove them from kernel config file and just add two following lines into your /boot/loader.conf.local: kern.ipc.nmbclusters="32768" kern.ipc.nsfbufs="32768" AFAIK 1024 is very-very small value for NMBCLUSTERS. -- Rgdz, /"\ ASCII RIBBON CAMPAIGN Sergey Osokin aka oZZ, \ / AGAINST HTML MAIL http://ozz.pp.ru/ X AND NEWS / \
