Hi all,
Using Solr 1.4 hosted with Tomcat 6 on Windows 2003 (sometimes Windows 2008)
Occasionally, we can't search anymore and this error shows up in the log
file:

Once we see the error, it is persistent. Restarting Tomcat makes the error
stop. This is happening across a variety of deployments and networks, so I
don't think there is an actual network problem. Many other apps operate
fine on the same server(s)/network(s).
We are using a file server (again with many different configurations) to
store the actual index files, which are not on the same machine as
Solr/Tomcat. On a few deployments we're moving the index local to Solr to
see if that corrects the problem.
My questions are:
1. Has anyone seen something like this before?
1. Is putting the index files on a file server a supported configuration?
Thanks for any help
Brian.
