Sorry to bother you hackers, but -questions isn't responding, and the handbook and Complete/Lehey don't, afaics, cover this situation explicitly. I can't really afford to screw up this production machine and start over from fresh disk, nor futz around for hours guessing what magik combo of post-install choices will do the trick. ========== I'm working, remotely, on a 4.1 system with only a binary install from cdrom. Now I need to do a custom kernal. Can the /stand/systinstall post-config option be used to put on all the developer source pkg without bothering the current config? which choice (I don't want X, just enough to build a custom kernal) It's in production as 200 K msgs/day mail hub. All I need to change, I think, is maxusers since we're getting this error from postfix: Nov 8 04:59:41 postfix/qmgr[16383]: fatal: socket: No buffer space available Nov 8 04:59:41 postfix/smtp[16872]: fatal: socket: No buffer space available Nov 8 05:00:58 postfix/qmgr[16876]: fatal: socket: No buffer space available The machine can get up 200 SMTP processes and 50 SMTPD processes simulatenously, 256 meg RAM. Increasing maxusers will fix this pb? afaic, maxusers can't be fixed with sysctl. Also, having been over /stand/systinstall a few times in last hour, there is no post-install choice that corresponds to an initial install "developer's sources less X and games", which is what I do when I install (this customer didn't follow my instructions for the initial insall). Also: On the postfix list, it seems someone has heard from several FreeBSD "experts" that FreeBSD should not be run at above maxusers = 128, while somebody else said they were running with 256 happily.
