Imunify360 failed to start with errors: "Start request repeated too quickly" / "Failed with result 'exit-code'"

Issue

Imunify360 cannot be started with errors like:

imunify360.service: Start request repeated too quickly.
imunify360.service: Failed with result 'exit-code'.

Environment

• Imunify360 v7.3.0

Solution

1. Check the output of `journalctl -u imunify360.service`. Most likely, `libssl` is broken and you will see:

imunify-service[3773042]: ImportError: /opt/alt/openssl11/lib64/libssl.so.1.1: file too short

2. If it is true, run the following commands:

# service imunify360 stop

# yum reinstall alt-openssl11 alt-openssl11-libs alt-curlssl11

# systemctl daemon-reload

# service imunify360 start

Cause

`libssl` is broken.
