I am using apache airflow in standalone mode with local executor with default setting and backend database is postgre.
The server i am using for airflow having sufficient resources 1Tb memory and 60 CPU cores.
But airflow will be shutdown after some time may be few hours or after one/two days by throwing below error.
error executing command4: Command ' airflow jobs check --job-type SchedulerJob --hostname "$(hostname)" ' returned non-zero exit status 127. Error executing command5: Command 'airflow db check' returned non-zero exit status 127.
Could anyone please suggest the solution on this issue?
