title: PM2 error occurred => exited with code [1] via signal [SIGINT]
body: <p>Nodejs was running on PM2 for a long time. And there is a corn which clears PM2 logs everyday</p>
  <pre><code>0 0 * * * find /home/user/.pm2/logs* -mtime +2 -exec rm -rf {} \;
  </code></pre>
  <p>Below error occurred for 1000 times and then pm2 stopped working and then when I reloaded the instance it was working fine as usual.</p>
  <p>What could be the reason for this error?</p>
