Sheng Yang commented on CLOUDSTACK-4540:
----------------------------------------
Please try it again, but increase the memory of mgmt server to at least 4GB,
and monitor the memory usage closely.
I've tried it locally, found java process can take more than 2GB during the
deployment process. And when that happen, the whole system would become very
slow, thus result in ssh timeout.
