Legato is not running after Roll-back

Legato Application Framework
1

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
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
