Subject "Bad file descriptor" Errors
Date Mon, 29 Nov 2010 21:17:57 GMT
Recently, we have started to get "Bad file descriptor" errors in one of our Solr instances.
This instance is a searcher and its index is stored on a local SSD. The master however has
it's index stored on NFS, which seems to be working fine, currently. 

I have tried restarting tomcat and bringing over the index fresh from the master (via snappull/snapinstall).


Any help would be greatly appreciated.

Thanks,
John
