Hmm, "Missing doc string" says you are trying to talk to what should
be an unpublishable method.  Is 'SIS/JSwift' likely to be the name
of a wiki page?  Have you perhaps upgraded Zope recently?  Also, what
version of the ZWiki product are you using?

As Chris pointed out, 'lib/python/ZODB/fsrecover.py' is the most
likely way to fix this.

  $ cd $ZOPE_HOME/lib/python
  $ python ZODB/fsrecover.py $INSTANCE_HOME/var/Data.fs

Of course, you make a backup of the (presumably) corrupt file, first.

Not common;  Chris noted one of the more likely causes (NFS
interfering with the storage's ability to perform reliable writes).
