First, your email is really broken and not replyable - the From: address was not a fully qualified domain name. Second, you really need watch those line lengths - 95 columns is a bit weird. Okay, now to your problem: the mb_map full is caused by there not being enough mbuf clusters. Try increasing "maxusers" in your kernel config file to something more appropriate (like say, 64 to start and if that doesn't fix it, try 100). This might also fix the "too many files" problem, but I'm not sure where that's coming from, so perhaps not. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
