relayer.service: Deactivated successfully.
Started relayer.service - Roller relayer service.

i think thats why relayer stopped
2:09
idk why it happened
2:10
i have changed Restart=on-failure to Restart=always
in the relayer.service (edited)
2:13
roller's services management is not reliable, roller shouldnt gracefully stop the service in case of error
2:17
mb this is a part of the health agent thought

bottom line is that the system services are set to only restart on on-failure vs always.
a note is that zonder shut down the health agent. not sure if this component should restart the relayer?

I want to know if you reset hub-rpc? Because according to the code, Service Relayer is only restart when reset hub-rpc. In the unhealthy case, DA-light-client will be restarted. @omritoptix @maxzonder
