`amazon-ssm-agent.service` keeps going `inactive (dead)`

[ryantepera]

I am running amazon-ssm-agent.service v3.3.2656.0 with the following systemd configurations on a RHEL 8 system

[Unit]
Description=amazon-ssm-agent
After=network-online.target

[Service]
Type=simple
WorkingDirectory=/usr/bin/
ExecStart=/usr/bin/amazon-ssm-agent
KillMode=process

# Restart the agent regardless of whether it crashes (and returns a non-zero result code) or if
# is terminated normally (e.g. via 'kill -HUP').  Delay restart so that the agent is less likely
# to restart during a reboot initiated by a script. If the agent exits with status 194 (reboot
# requested), don't restart at all.
Restart=always
RestartPreventExitStatus=194
RestartSec=90

[Install]
WantedBy=multi-user.target

But it seem my ssm agent consistently runs into the problem where it goes inactive with the following terminated signal

amazon-ssm-agent got signal:terminated value:0x7f292bd0ce20

I'm not sure what value:0x7f292bd0ce20 indicates and was hoping someone could answer that for me.

Here is a full journalctl -u log:
