Simon Willnauer commented on SOLR-2247:
---------------------------------------
As uwe pointed out correctly on IRC that problem might be somewhat "solvable"
if you use MMapDirectory since it only with run into this exception when you
open the files initially. Once that is done its mapped and you should be fine.
Yet, it somewhat requires 64 JVMs.
just a hint...
