This is implemented, by using the option Restart=on-failure. Eventually, also RestartSec= can be used. - when the service is configured to restart itself (as above), the number of restarts count must be limited (example: 3 restart retries). At the moment, this can't be done, there aren't any options implemented for this situation, the service keeps restarting forever. - when a service is configured to restart itself on failure (as above), after the restart retries expire (example: after 3 restart retries), then if the service is still failed, some action could be taken (optionally), to run a command (something like ExecStopPost=). At the moment, this also can't be done. So, for these last two features I created a patch, which adds two more options for a .service : - RestartRetries=n (where n is the number of restart retries) - ExecPostRestarts=/some/cmd (where the command "/some/cmd" will be executed after restart retries are finished). The systemd's behavior is modified as follows: - when service is in auto-restart state, each restart attempt is counted until the maximum restart retries are reached (specified via RestartRetries option); - when max. restart retries are reached and the option ExecPostRestarts isn't specified, the service enters dead state; - if a command is specified in ExecPostRestarts option, then after auto-restart state (when max. restart retries are reached) the service will enter a new state post-auto-restart and will remain in this state as long as the specified command is executing; - when post-auto-restart command ends execution, the service enters dead state. We would appreciate if you can add this patch in your development tree. Currently this patch is made for systemd-16. If you agree we will send you the patch after following an IP review in our company. Thanks in advance, Cristian Patrascu Wind River </body> </html>
