Hi,
I have setup OODT filemanager on port 9000, using SOLR as the indexing service 
on port 8081. They are both setup on the same computer, while crawler runs on a 
number of different compute nodes spread across the local network and the cloud.

When the crawler runs and ingests files I notice that there are several 
connections that open to solr and remain in CLOSE_WAIT state for hours.
any idea why this happens? Moving forward I am planning to use several hundreds 
of crawler instances, each running on different computer, that will create 
thousands of such connections and will probably create problems to the system.
Thanks in advance for any help
Kostas
