Hi Bosko, Looking at netstat -m, the value I'd probably be interested in is the following: 3% of cluster map consumed knowing that the Maximum possible is 25600 I can deduce that ~768 are being used? Is that correct. I'm not much of a programmer, but I did recognize the printf(); statements from a C class I didn't do well in half a decade ago... as you can tell, I'm not much of a programmer :). If it's not the 3% I should be paying attention too... then let me know :) As for using the option DDB in my kernel, I do have one question. I do have remote console access that I use to go into single user mode on the box remotely. I'm suspecting I could use the debugger mode over the comconsole... I just want to make sure there is some kind of reboot command from the debugger so that I can tell the box to reboot once I've captured the stack trace? If so, I'll enable the DDB tonight and get you the info as soon as I can. thanks again, Stephane. ----- Original Message ----- From: "Bosko Milekic" <bmilekic@technokratis.com> Newsgroups: mailing.freebsd.current Sent: Wednesday, July 23, 2003 9:28 Subject: Re: FreeBSD 5.1-R kernel panic > > On Wed, Jul 23, 2003 at 09:24:24AM -0600, Stephane Raimbault wrote: > > Thanks Bosko, > > > > I've changed my /boot/loader.conf to reflect the kern.vm.kmem.size option. > > > > kern.vm.kmem.size="350000" > > > > As far as changing the nmbclusters, I'm not sure how many I use now.
