I have a server that currently is hitting its limit of vnodes:

Aug 31 17:33:01 venus root: debug.numvnodes: 519920 - debug.freevnodes: 9256 - debug.vnlru_nowhere: 253542 - vlrup
Aug 31 17:34:00 venus root: debug.numvnodes: 519920 - debug.freevnodes: 9110 - debug.vnlru_nowhere: 253561 - vlrup
Aug 31 17:35:02 venus root: debug.numvnodes: 519920 - debug.freevnodes: 8668 - debug.vnlru_nowhere: 253580 - vlrup

Its been up for 25 days now ... is there a way of 'flushing' vnodes? for
instance, if I were to shut down all of the processes on the machine, is
therer something like 'sync' that I could run that would flush all the
vnodes before starting up the processes again? Without doing a reboot?

Thanks ...
