Legato is not running after Roll-back

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
