Can you try your NFS mounts from directly within the jails, or stop one
or more jails for a night and see if it becomes stable?  Anything else
unusual besides the jails/nullfs such as pf, ipfw, nat, vimages?  My
systems running 10 seem fine including the one running poudriere builds
which uses jails and I think nullfs, but not nfs.  Do mbufs go up when
you cause nfs traffic?
