@stephenw10 - Thank you Stephen for taking the time to reply. The following is an update for anyone who comes across this which may benefit from this exchange.
No matter what I tried i could not get rid of the crash. I noticed this usually happens when the firewall is under heavy use. Normal use usually did not result with the issue.
In the end I decided to change the machine and now using Intel(R) Core(TM) i5-8500 CPU which has been working with no issues for few days now. I know this is way overkill, but the lower powered ones were problematic.
As for your question on:
Do you see the file /var/etc/xinetd.conf present on the system?
I moved into a different system and don't have access to that install anymore hence i can not answer it.
