Hello, It isn’t a very frequent, but sometimes I have this important problem. After a Reboot command, sometimes a rollback occurs(I don’t know why…). Sometimes, the rollback run OK, but sometimes Legato is not running after the reset. In addition, if I try start legato, this doesn’t run and indicates this error: ![legato](https://us1.discourse-cdn.com/flex019/uploads/legato1/original/1X/449e144f10ee65899aff8e08e1fa77d37d602fa2.jpeg) I can see that rollback try run because in /legato/systems/current/apps is the golden apps. It is very important. I lose the remote when this occurs. Thanks ---

@Riegosalz, According to the logs, it seems you are missing /etc/resolv.conf What is the output for : **cm info** **legato version** **fwupdate query** Are your custom applications built with the same legato version as the one running in the module? ---

@Riegosalz, What is the current status of this issue? I think it was solved via SF, right? ---

Hello, The problem is the size of the configtree. If the configtree too much big, then, while the app is run there isn`t problem, but if you restart the system, the configtree cann’t load, and legato don’t run. pro tem, we have done smaller the config tree. greetings
