You would nisser:/usr/src/sys/i386/conf$ grep maxfiles LINT nisser:/usr/src/sys/i386/conf$ grep maxusers FORSETI maxusers 10 #32 Ahhh, if only I had activated that :(. So given your formula, which does ring a bell albeit faintly, that would mean MAXUSERS defaults to 10. I can live with that, but I think the formula is to weak for interactive GUI use. Tentatively I would say it has to be 32 and in our specific case more like 160. Anyway, where is the description of these params if not in LINT? On a whim I would say the manual and whaddayaknow a direct hit. It even has the same formula although now attributed to the maximum number of processes. No trace of MAXFILES though. I'll keep looking but any pointers will be appreciated. Even though it'll probably be some .h param. Roelof -- Home is where the (@) http://eboa.com/ is.
