For one thing, if you've got a machine with 256MB of RAM, you cannot possibly be able to dedicate 256MB just to kern.ipc.maxpipekva. Likewise, a machine with 256MB of users would auto-tune kern.maxusers to ~100 or so, and kern.maxfiles ought to be under 10000, if not half that. You should revert to the defaults and make gradual tuning changes, if needed, from there. -- -Chuck _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
