As you can see, my A40I-GN process does not exist, monit tries to start it, after executing my script, I can see from the log that the A40I-GN process is started, but when I check the status, my A40I-GN process is not started

Please note the timestamp. monit tries to restart process A40I-GN and then execute my script. I see in the log "[1970-01-01T14:03:09+0800] debug: 'A40I-GN' started ', but after 10 seconds (I set the monit scan period to 10s), monit tried again to restart A40I-GN. I tried to manually execute the script I had written, and the process A40I-GN could run in the background

hi！
I tried to modify my script file and monit can start the process A40I-GN normally
Before :/A40I/ a40i-gn /A40I & （monit cannot start A40I-GN）
Now :nohup /A40I/A40I-GN/ A40I-gn > /dev/null &
I wonder why this is so

monit requires that the start program will daemonize the application (run in background and detach from the controlling terminal)

The log excerpt doesn’t show what happened after the restart attempt … normally Monit waits for the start to finish or timeout. Did the start time out?
If it didn’t timeout, please check logs of the application being started. Monit just logs the start and error output, which showed some startup activity.
