Hello,
We are using Solr(v 1.3.0 694707 with Lucene version 2.4-dev 691741)
in multicore mode with an average of 400 indexes (all indexes have the
same structure).
These indexes are stored on a nfs disk.
A java process writes continuously in these indexes while solr is only
used to read those indexes.
We often got this exception :
HTTP Status 500 - No such file or directory java.io.IOException: No
such file or directory at java.io.RandomAccessFile.readBytes(Native

How can we avoid this problem ?
Thanks
