What do you have for hour _softcommit_ settings in solrconfig.xml? I'm
guessing you're using SolrJ or similar, but the solrconfig settings
will trip a commit as well.
For that matter ,what are all our commit settings in solrconfig.xml,
both hard and soft?

Hi Joshi;
Click to the Plugins/Stats section under your collection at Solr Admin UI.
You will see the cache statistics for different types of caches. hitratio
and evictions are good statistics to look at first. On the other hand you
should read here:

You would get more room for disk cache by reducing your large heap.
Otherwise, you'd have to add more RAM to your systems or shard your index
to more nodes to gain more RAM that way.

What operating system are you using, and what tool are you looking at to
see your memory usage? Can you share a screenshot with us? Use a file
sharing website for that - the list generally doesn't
