Subject Re: Issue while restarting from SavePoint
Date Wed, 19 Oct 2016 08:19:20 GMT
Hey Anirudh!

As you say, this looks like two issues:

(1) In detached mode the configuration seems to be not picked up
correctly. That should be independent of the savepoints. Can you
confirm this?

(2) The program was changed in a non-compatible way after the
savepoint. Did you change the program and if yes in which way?

– Ufuk
