Could there be some bashism in the script that makes it hang?
You could also remove the redirections to /dev/null of stderr in that
command to see the actual error. It's better first to check the script
with /bin/bash to see if it succeeds.

I have no explanation yet, though it cannot be the entropy pool issue as
/dev/urandom is used. However to identify the issue I'll need some debug
data from you, e.g., by running the instance that fails without
redirection of stderr and using -d 9, both on the client and server.
