Subject RE: Solr Not releasing memory
Date Mon, 03 Sep 2012 22:47:20 GMT
You've got more than 45GB of physical RAM in your machine? I assume it's actually virtual memory
you're seeing, which is not a problem, even on Windows. It's not uncommon for resident memory
to be higher than the allocated heap space and it's normal to have a high virtual memory address
space if you have a large index.
