Let’s say I’ve encountered the following entries in pbm-agent logs, I can’t seem to find anywhere how to make sense of why the kill happened?

```auto
Jan 24 12:33:27 ip-xxx-xxx-xxx-xx.us-west-1.compute.internal systemd[1]: pbm-agent.service: main process exited, code=killed, status=9/KILL
Jan 24 12:33:27 ip-xxx-xxx-xxx-xx.us-west-1.compute.internal systemd[1]: Unit pbm-agent.service entered failed state.
Jan 24 12:33:27 ip-xxx-xxx-xxx-xx.us-west-1.compute.internal systemd[1]: pbm-agent.service failed.

```

status=9 refers to something? The documentation doesn’t seem to be extensive and I’m a bit lost on where to look.

Hi, you may want to check your server logs in /var/log to see if OOM-killer or something else killed it
