CacheClosedException: The cache is closed

I've found this problem in my applications.

The problem is that i found this exception when the application try to do a put in a Gemfire Region. I attache the exception.

In the gemfire.log ican see that the Cache was started a few days before the application crash and in the last lines i can see this line.

[info 2013/09/06 07:59:09.570 ART gire-kiosk <Distributed system shutdown hook> tid=0xf] VM is exiting - shutting down distributed system

[info 2013/09/06 07:59:09.571 ART gire-kiosk <Distributed system shutdown hook> tid=0xf] GemFireCache[id = 10905179; isClosing = true; isShutDownAll = false; closingGatewayHubsByShutdownAll = false; created = Mon Aug 26 15:45:20 ART 2013; server = false; copyOnRead = true; lockLease = 120; lockTimeout = 60]: Now closing.

But I can't found the reason by the cache is close.
