Hi
We are still getting various issues on our Lucene indexes running on an NFS
share. It has taken me some time to find some useful information to report
to the mailing list.
I have created a test application which is running on two Linux servers.
The Lucene index is on an NFS share. After running for some time, both
instances throw this exception:
Caused by: java.io.FileNotFoundException:

directory)

I have enabled the info stream on the IndexWriter object using
IndexWriter.setDefaultInfoStream(). The output from the two servers is as
follows:

I have added logging to our ExpirationTimeDeletionPolicy and I don't think
it is deleting the "_zr.cfs" file.
Once again, I would really appreciate your help solving this issue,
Thanks for your help,
Patrick
