There are times, when you might suddenly see your Odoo is shutdown automatically, without warning. Once you enable to logging, you could see an error like the following:
virtual real time limit (151/120s) reached.
or in full details like the following

This is because Odoo is killing zombie processes and probably mistakenly crashing your Odoo completely while doing so. The parameter that is used for this purpose, can be found in Odoo documentation:
https://www.odoo.com/documentation/14.0/reference/cmdline.html
--limit-time-real <limit> Prevents the worker from taking longer than <limit> seconds to process a request. If the limit is exceeded, the worker is killed. Differs from --limit-time-cpu in that this is a “wall time” limit including e.g. SQL queries. Defaults to 120.
You may start your service command with something like –limit-time-real 100000 to avoid Odoo from auto killing processes. A command could look like the following if you edit your service file located at:
/etc/systemd/system/odoo14.service
The exec would be like the following:
ExecStart=/usr/bin/scl enable rh-python36 -- /opt/odoo/odoo14-venv/bin/python3 /opt/odoo/odoo14/odoo-bin -c /etc/odoo.conf --limit-time-real=100000
Once the change is done, save the file, and reload the system daemon and restart your Odoo
systemctl daemon-reload service odoo14 restart
