Content

When trying to RE from an AWS RDS instance e.g. through ssh tunneling with an EC2 instance it's been discovered that the RE process was crashing.

Technical details

The connect function is currently trying to always setup the ssh tunnel when it's called thus the function can't be called twice in the same RE process because we try to re-setup the ssh tunnel twice and it's failing with a weird error. (Maybe it means we need a better connectivity management but that's another story...).
