Depends on how the systems is used, to some extent. You probably won't notice it as long as it doesn't get ridiculously large. I realize that statement is a circular definition, but an accurate answer would, well, depend on how the system is used. > What will be an acceptable value for NGROUPS_MAX? > I know this number is set to 32 in suse linux....

If your application really requires this sort of thing, 5.x might be more stable for your application than 4.x. Or maybe you should describe how you're getting to need so many groups, and see if someone can suggest a better way without the groups... > About how doing that change... > Is it just about changing the value and reboot the machine or there is some > recompilation matter linked to that change? You have to rebuild everything that uses it, of course. I'd recommend a full system rebuild. http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html -- Lowell Gilbert, embedded/networking software engineer, Boston area: resume/CV at http://be-well.ilk.org:8088/~lowell/resume/ username/password "public" _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
