Many processes stuck in zfs

[Ollivier Robert]

According to Stefan Bethke:
> $ sysctl kern.maxvnodes vfs.numvnodes vfs.freevnodes
> kern.maxvnodes: 100000
> vfs.numvnodes: 87681
> vfs.freevnodes: 7600
> 
> Is there a rule of thumb what maxvnodes should be tuned to?

Not sure, I max'ed it to 200000 and the machine has not locked up since.  Try that, 300000 if not and so on.  The thing is, receiving snapshots is going to generate a lot of inodes/directories so vnodes shortage may be your problem.
