Michael McCandless commented on LUCENE-4467:
--------------------------------------------
You can run CheckIndex -fix, to recover the index: it will delete any segments
that it detects corruption in.
Yes, only one IndexWriter at a time may have the index open, regardless of
whether the IndexWriters are in the same or difference processes. The 2nd
IndexWriter will wait until lock timeout has elapsed and then give up. The
logic is very simplistic, and is really designed to protect the Lucene index
from corruption, not to make it easy to coordinate writing from multiple
writers.
But it looks like you hit corruption with a single writer? Can you turn on
IndexWriter's infoStream, and next time the corruption happens, post that log?
Is this a local or remote filesystem? Can you try upgrading Java (1.5.0_13 is
quite old) ...

> We're using lucene to index XML. We've had it in test on a server for some
> weeks with no problem, but today we've got the error below and the index
> seems no longer usable.
> Could you please tell us
> 1) is there a way to recover the index?
> 2) is there a way to avoid this error?
> I can supply the index if needed
> many thanks
