Re: bpvo pool exhausted

Hello,

I do not have a way to consistently reproduce this. I was finally able 
to get through recompiling all of the installed ports before I was able 
to test this.

Should this show up via sysctl? Because it does not:
sysctl machdep.moea64_bpvo_pool_size
sysctl: unknown oid 'machdep.moea64_bpvo_pool_size'

Should I be able to set this in /boot/loader.conf?

I did try setting it at boot. I'm not sure it did anything though. 
Nothing in dmesg.

The VM has 12 threads and 16GB of memory running 13.1-RELEASE-p2.

Maybe this is a new option in CURRENT?
