Nope, there is an initialized vnode on the freelist. Something that
should never be possible because clearing a vnode is in the same RVM
transaction as moving it to the freelist. Somehow it happened here, now
I don't know whether this vnode is actually free, or was picked up from
the freelist and is being used in some volume.

In case it's really free, we could clear it. If it is used we should
take it out of the freelist. The scary thing is really that the
atomicity guarantee of RVM was broken, otherwise we would never get into
this state.

First of all, we better check with 'norton' what is going on.

$ norton -rvm <rvm log> <rvm data> <rvm data size>
norton> show free large

This should give how many large vnodes are on the freelist and will
dump the contents of any vnodes that are non-zero.

Did you purge the volume, or delete the individual files/directories.
Was the client connected or write-disconnected (reintegrating).
