Quarantine Management

I have problems in my quarantine management. I have SMSME 6.5.8.285 and MS Exchange 2010.

1. In my server status I seen 43932 messages in quarantine. server status.png
2. In quarantine number of items appeared 90 messages. quarantine number of items.png
3. In quarantine items in explorer physically appeared 43932 messages. quarantine items in explorer.png
4. Στο event log I have messages saying my quarantine is full. event log.png

In my quarantine settings I have 60000 messages or 500 Mbs in which none of them is fullfiled at the current time.

Is anyone can explain this phenomenon?

Thanks
