Hi Martin, Thanks for the quick response on this! I cannot see any problems in the dependency definition, anyway I will investigate this further and get back to you soon.

Looking at the startupOrder in the cartridge group I am not sure that this is proper stratos way to define multiple dependencies in stratos (I also posted it right below) ? Btw, I couldn’t find a stratos sample which defines dependencies between more than 2 cartridges ?
