 I can confirm that this still occurs, this time on 8.3-RELEASE on amd64.
 
 Exactly as described by the previous submitters - nothing special going on 
 on our system (no NFS, etc.) - just plain old snapshots being created and 
 removed and ... eventually some .zfs/snapshot directories just disappear.
 
 Two things:
 
 1) In our experience, enough retrying of ls/find/etc. of the missing 
 snapshot directory will eventually lock the system up
 
 2) non-critical severity is incorrect - snapshots are a critical feature 
 and this is a critical bug.
 
 Thanks.
