Validate config_db json file before config reload
What I did
Check config_db json file before stopping the services. If there is an error, DB wont be able to connect to any services
How I did it
Run the SONIC_CFGGEN_PATH to all the one or more config_db.json file. If there is any error, it will come out of config reload loop before stopping all the services.
How to verify it
Create an error in config_db.json and we should see any error before all the services go down.
Previous command output (if the output of a command-line utility has changed)
Suppose there is an extra "," issue in one of the config_db.json file and when we issue 'config reload' there is no validation for config_db.json file. Only when DB services will restart and encounter issue it will flag it but it has brought all the services down. Now none of the services will start and most of the commands wont run and system will hang when we issue config reload or reboot.

We do have json validator: https://github.com/sonic-net/sonic-utilities/blob/master/config/main.py#L1559 That is in each config consumption. If you want to validate the json in the beginning, you also need to consider this L2 case as stdin can only be read once. https://github.com/sonic-net/SONiC/wiki/L2-Switch-mode If you read it during validation, the later read content will be empty:
cat <<EOF | sudo config reload /dev/stdin -y
