Subject RE: Solr Not releasing memory
Date Mon, 03 Sep 2012 15:39:17 GMT
I am taking of Physical memory here, we start at -Xms of 2gb but very soon it goes high as
45Gb. The memory never comes down even when a single user is not using the system.

Regards,
Rohit

It would be helpful yo know which memory isn't being released. Is it virtual or physical or
shared memory? Is it the heap space?
