Huge Index - RAM usage?

[Antonio Lobato]

Hello everyone!

I have a question about indexing a large dataset in Solr and ram  
usage.  I am currently indexing about 160 gigabytes of data to a  
dedicated indexing server.  The data is constantly being fed to Solr,  
24/7.  The index grows as I prune away old data that is not needed, so  
the index size stays in the 150-170 gigabyte range.  However, RAM  
usage on this machine is off the wall. The usage grows to about 27  
gigabytes of RAM over 2 days or so.  Is this normal behavior for Solr?

Thanks!
