title: When overFlowToDisk gets activated in EHCACHE?
body: <p>I have some questions on "overflowToDisk" attribute of  element?</p>
  
  <p>1) I read at this <a href="http://ehcache.org/documentation/configuration.html" rel="noreferrer">URL</a> that :</p>
  
  <p>overflowToDisk sets whether element can overflow to disk when the memory store has reached the maximum limit. </p>
  
  <p>"Memory" above refers JVM memory allocated for Java process running EHCACHE, or is there any parameter in  to specify Cache memory size?</p>
  
  <p>2) When the poces running EHCACHE terminates for some reason, whether this disk gets cleared and everything in cache gets vanished?</p>
