:I have a semi-production machine running stable from a few months ago. 
:The vnode related sysctl values on this machine are;
:kern.maxvnodes = 36053
:kern.minvnodes = 9008
:However on the machine I'm having problems with they are; (current stable)
:kern.maxvnodes = 16754
:kern.minvnodes = 4188
:I've added the previous settings to /etc/sysctl.conf and the problems 
:have not reoccurred. I can now run "cd /usr/pkgsrc && cvs -q update -dP" 
:without problems, previously this would result in a lockup without failure.
:I only have standard mounts and am only working within /usr.

:Do you still want a kernel core?

    Yes.  With the larger vnode values... whatever reproduces the lockup
    the best.  Clearly there is something going on here that needs to be
