What's going wrong?

I have the following config for an application

{
        name: "indexer",
        script: "./indexer/indexer.js",
        error_file: "./logs/indexer.out.log",
        out_file: "./logs/indexer.out.log",
        log_date_format: "DD-MM-YY HH:mm:ss",
        instance_var: 'INSTANCE_ID',
        cron_restart: "*/5 * * * *",
        autorestart: true,
        stop_exit_codes: [0]
}

Indexer only takes 10 seconds to run. I want it to run once every 5 minutes, but it should start again in case the system reboots and resurrect is called. The config looks right as per the docs, but stop_exit_codes = [0] doesn't seem to work. In the pm2 logs I can see that indexer indeed exits with code 0, but still it keeps running indexer every 3-4 seconds. This is the output of pm2 logs:

PM2        | App [indexer:5] exited with code [0] via signal [SIGINT]
PM2        | App [indexer:5] starting in -fork mode-
PM2        | App [indexer:5] online
5|indexer  | 10-05-23 17:27:55: hello
PM2        | App [indexer:5] exited with code [0] via signal [SIGINT]
PM2        | App [indexer:5] starting in -fork mode-
PM2        | App [indexer:5] online
5|indexer  | 10-05-23 17:27:58: hello

How could we reproduce this issue?

1. Use the config I provided and run the application once
2. pm2 save
3. pm2 kill
4. pm2 resurrect

See #5208

This is a different issue where I don't get an error, but at the same time it fails to stop the restarting even after exit status 0

same issue on 5.3.0

same issue on 5.3.0

install the dev version resolve this problem npm install -g github:Unitech/pm2#development

same issue on 5.3.0

It does not work with stop_exit_codes: [0], and works with any other custom exit code, i.e. stop_exit_codes: [42],. Tests for this feature in the repo check for stop_exit_codes: [12, 42], so they don't reach problem with exit code 0 (I guess).

UPD: For strange unknown reason, setting stopExitCodes: [93],, changing app, then setting stopExitCodes: [0], and changing app again made it work. Maybe configs are cached?..
