Re: Reclaiming vnodes


Vnodes are only allocated and there is no vnode recycling. If number of used vnodes in a system is > than kern.vnodes_num_hiwat(in percents of maxvnodes) vrele thread will be woken up and it will start with releasing of free vnodes until number of used vnodes is < than kern.vnodes_num_lowat.

And how will that help the situation?

As far as I understand the situation the system is in a state that it can't
handle the amount of resource requests forwarded to it, and thus will probably
need to sleep on the request for some new vnode anyway.  Maybe you are shifting
the problem a bit further along, but it doesn't help in principle anyway.
