Seem that it was the cloning which take too much time. (I think around 1 min sometimes),
they the cfs lock got a timeout error.

(I think that lock timeout is enforced).

I have change my netapp plugin code to do it faster (around 10s), no more problem now.

Thanks for help.

Maybe. Try to add something like: 

syslog('info', 'aquire lock'); 
... 
syslog('info' 'release lock'); 

to cluster_lock_storage() for debugging.
