Failed to start MariaDB 10.2.13 database server

I’m currently trying out ERPNext Production in a virtual box environment (to be deployed in a garment manufacturing entity) , everything works fine for a day or two and I get error while booting the virtual machine “Failed to start MariaDB 10.2.14 database server”

Opening Localhost:8080 in browser gives an “Internal Server error”

Trying to update frappe bench results in “Errno111”

Tried the following fix without any success
" [solved] MariaDB 10.1 to MariaDB 10.2 upgrade crash "

This happened to me on three instances of my trial.

Is there any updated solution for the problem?
