RMAN backup to ZFS is hanging while writing the backup piece.

The RMAN Backup of the controlfile to local filesystem is not hanging while the backup to ZFS is hanging all the time.

Taking RMAN out of the picture, the copy of a file via Operating System commands to ZFS is also hanging.


 The kernel of the server trying the backup was upgraded to 2.6.39-400.248.3.el6uek.x86_64.
