Yes, this is a known problem, cfs disconnect puts a software filter in 
the rpc2 layers, but reconnect fails to clear it.

Use 'filcon clear -c localhost' to get rid of the filter without 
restarting venus.

That also happens if /coda is still mounted. We cannot force the kernel 
to unmount when some processes still have references to files in the
/coda tree, and the kernel module doesn't allow a new venus to take 
over an existing mount.

I often use 'lsof | grep /coda' to find which processes need to be 
killed off, and then 'umount /coda', before starting venus.
