'netstat -m' You can access the relevant sysctls directly; take a look at the way netstat does it in src/usr.bin/netstat/mbuf.c > Also, I took a quick look at the developers handbook and couldn't find just > yet what I needed to change to the kernel to provide a stack trace... do you > know what options I should be adding to my kernel?

At the very least, you need "options DDB". This will drop you into the debugger on a kernel panic, at which point you can just issue 'tr' to get a stack trace. Be careful, if you only have remote access to the machine, this is generally not a good idea. > Thanks, > Stephane. -- Bosko Milekic * bmilekic@technokratis.com * bmilekic@FreeBSD.org TECHNOkRATIS Consulting Services * http://www.technokratis.com/
