James has suggested the most likely cause by far.

There's a small possibility that a corrupted database could also cause
this error.  Corruption could be due to:

* a Xapian bug (though I don't think I've ever seen that).

* running two updates at once.  To manage this the locking would have to
  not work - it should be NFS safe, but perhaps some FS with odd
  semantics could cause this.  Or maybe someone just deleted the lock file.

* a software (e.g. operating system) or hardware problem.

Try running quartzcheck on the database.  If it reports problems, then
you'll have to rebuild the database I'm afraid.  If not, I'm not sure
what's going on.  How big is the database?
