RHEL 7.4 and 7.6 mysteriously deleting jar files

RHEL 7.6 and 7.4 are mysteriously deleting jar files after we use Flexera to install a company product. It does not show this behaviour on any other version of Linux, including Centos 7.

The directory it's being installed to is /usr/local/bin/MY_COMPANY.
We've also tried /var/opt.

The jars are deleted after five minutes exactly.

Any ideas?

Do you have a cron job that runs every 5 or 10 minutes?

crontab -l
