[JuTiger-Lee]

Is there an existing issue for this?

• I have searched the existing issues

Current behavior

I'm doing Graceful Shutdown in pm2

test process

1. Database record lock in workbench
2. lock wating in nestjs application
3. excute command pm2 restart different terminal
4. lock clear(excute command is "ROLLBAKC") in workbench
5. excute query in nestjs application
6. excute error message "[TypeORMError: Connection is not established with mysql database" in nestjs application

I know why this problem occurs because nestjs lifecycle
but I think @nestjs/typeorm libary should db connection handling

I tried typeorm config keepConnectionAlive options to fix true
Is there a way that I don't know about?
