Moving to 0.3.7 has broken checkout on remote nodes. They fail reporting unable to checkout the code after a 10 minute timeout.
In the log on the gerrit server are hundreds of lines saying:
WARN com.google.gerrit.httpd.ProjectBasicAuthFilter : Authentication failed for Username for 'https: account inactive or not provisioned in Gerrit
So it appears that the remote node is using the wrong credentials to try to do the checkout.
Reverting to .03.5 and everything works fine
