I will try it ASAP, in the meantime the new behavior of the NetAPP has been disabled,
and since I still don’t know what is causing the unexplained huge number of unlock requests,
it’s going to be a long debug process.
also, I will see how to switch to TCP for the NLM protocol with minor disruption.
