Have I done my calculations right?? (64 * 1024) = 65536 bytes (65536 * 8) = 524288 bits After trying the above I get no buffer space availble errors. After a lot of trial and error i found the biggest value I can give without running out of buffer space is in between 233000 and 235000. Can I increase the buffer space?? Would this be a good idea?? Is it better to give a number that is a power of two?? Chris Moline To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
