Resin Logs: regarding LRU while in use (use-count=1). Consider increasing session-count

[Alan Yap]

Hie all,

I've just downloaded a copy of the stdout log files from my hosting to aid me in ironing out some bugs. But the fragment of logs below worries me (logs info truncated for security purpose :

[19:34:05.562] /home/alanyap/resin-pro-3.1.2/webapps/WEB-INF/classes/myclass/myobj.class length is modified (7789 -> 8020)
[19:34:05.562] WebApp[http://localhost:xxxx/app1] stopping
[19:34:05.564] /home/alanyap/resin-pro-3.1.2/webapps/WEB-INF/classes/myclass/myobj.class length is modified (7789 -> 8020)
[19:34:05.564] WebApp[http://localhost:xxxx] stopping
[19:34:05.567] /home/alanyap/resin-pro-3.1.2/webapps/WEB-INF/classes/myclass/myobj.class length is modified (7789 -> 8020)
[19:34:05.567] Host[] stopping
[19:34:05.567] WebApp[http://localhost:xxxx/app2] stopping
[19:34:05.567] session abcHWf2WLhDgAeLBRytjs LRU while in use (use-count=1).  Consider increasing session-count.
[19:34:05.567] session abcIEPwUaTGgzdmBK7sjs LRU while in use (use-count=1).  Consider increasing session-count.

As you all can see, I had overwritten a new copy of myclass/myobj.class in the host and Resin detected the changes, thus stopping and restarting all webapps.

But what does the last 2 lines mean? I tried googling for answer but can't seem to find any information on how to increase my "session cache". And are those lines directly related to webapp "app2"? My first assumption would be there are two live sessions in "app2" while Resin is restarted, and they're killed (obviously), and those 2 lines are merely friendly messages informing me that. But I can't leave things to chances.

Hope I can get a concrete explanation here. Thanks
