   You may also wish to try to get the problem to occur sooner after boot
on a non-patched system by doing a "tar cf /dev/null /" (note: substitute
/dev/zero instead of /dev/null, if you use GNU tar, to disable its
"optimization"). You can stop it after it has gone through a 100K files.
Verify by looking at "sysctl vfs.numvnodes".
   Doing this would help to further prove that lots of allocated vnodes
is the prerequisite for the problem.
