Sheng Yang commented on CLOUDSTACK-4540:
----------------------------------------
It's different case about NetworkUsage command, which wouldn't block the other
execution(and in another thread).
Also, please check if "execute.in.sequence.network.element.commands" is set to
"true" per previous discussion, and if server has enough memory(at least 4gb).
