Heap size and Solr 4.3

Hi All,
we have deployed on our production environment a new Solr 4.3 instance 
(2 nodes with SolrCloud) but this morning one node gone on outofmemory 
status and we have noticed that the JVM uses a lot of Old Gen space 
during the normal lifecycle.

What are the items that improve this high usage of Heap?

Thanks,
Marcello

Marcello,

Can you quantify what you're seeing?  Did you send the JVM any args (Xmx,
Xms, etc)?

Thanks, Ryan
