Recordings get deleted automatically after some time

[Darshit Patel]

Hi,
I am using open meeting version 3.3.0
I have recorded open meeting conference room. Initially recording was
stored in stream/<room_id>/<file_name>.flv
But after some time it is automatically get deleted.
I have also checked hibernate folder it is not there.
Is there any configurations or changes regarding this in version 3.3.0?
