Max Memory Threshold Auto Reload

PM2 allows to reload (auto fallback to restart if not in cluster) an application based on a memory limit/ Please note that the PM2 internal worker (which checks memory), starts every 30 seconds, so you may have to wait a bit before your process gets restarted automatically after reaching the memory threshold.

CLI:

pm2 start api.js --max-memory-restart 300M

Config file (ecosystem.config.js):

module.exports = {
  apps: [{
    name: 'api',
    script: 'api.js',
    max_memory_restart: '300M'
  }]
}

Note: Units can be K(ilobyte), M(egabyte), G(igabyte).
