shiro-activeSessionCache.data file has become extremely large (2GB)

[ApacheNinja <dp...@gmail.com>]

Hello,

In our root directory on our web server there is a /tmp folder.   Inside the
tmp folder is another folder called shiro-ehcache.  The file inside
shiro-activeSessionCache.data has grown to almost 2GB in one day.  We have
restrictions on our server and if contents in the folder become too big then
IT receives warnings.  I was not aware that Shiro was writing to the /tmp
directory.   Is there a reason why this would be happening all of a sudden? 
We are using EhCache when setting the cache on the security manager.  Would
it be Shiro doing this or EhCache?  Any help would be greatly appreciated. 
Thank you.

After further investigation, it appears that it ran out of memory and thus
had to write to disk.  It is unclear why this would all of a sudden start
happening though.  

These are the settings for our Shiro session cache in our ehcache.xml file:

   <cache name="shiro-activeSessionCache"
       		maxElementsInMemory="10000"
       		overflowToDisk="true"
       		eternal="true"
      		timeToLiveSeconds="0"
       		timeToIdleSeconds="0"
       		diskPersistent="false"
      		diskExpiryThreadIntervalSeconds="600"
      	 	>
    </cache>

I was contemplating turning off session caching but I believe that made the
application slower when attempted previously.  Any suggestions on fine
tuning this so that I don't consistently have a huge log file?

Here is how we are initializing everything programmatically:

public static void initSecurityManager() {
		 
		        //Set realms
			mSecurityManager = new DefaultSecurityManager();
			mSecurityManager.setAuthenticator(new MockAuthenticator());
			ArrayList <Realm> realms = new ArrayList<Realm>();
			realms.add(new PortalRealm());
			realms.add(new PortalBaselineRealm());
			mSecurityManager.setRealms(realms);
			
			//Setup caching
			SessionDAO sessionDAO = new EnterpriseCacheSessionDAO();
		
((DefaultSessionManager)mSecurityManager.getSessionManager()).setSessionDAO(sessionDAO);
			EhCacheManager shiroCacheManager = new EhCacheManager();
			mSecurityManager.setCacheManager(shiroCacheManager); 
		
		  //Set session timeout	

((DefaultSessionManager)mSecurityManager.getSessionManager()).setGlobalSessionTimeout(28800000);
			
			SecurityUtils.setSecurityManager(mSecurityManager);
	 }
