I have uninstall the latest java version and install the previous one on the failing node and … it works !!!
so apparently it means that ROR for elastic 6.8.1 is not compatible with the latest java OpenJDK 64-Bit Server VM (build 25.262-b10, mixed mode.
Maybe you can build a new ROR version adding the missing java rights ?
It would be great if you could do that
Thanks
