There was a problem hiding this comment.
The crash is not cause by a behavior change, python version sonic-db-cli also crash in this case, access name space DB need name space config file ready.

Why I did it
Fixe #12047. After the c++ implementation of the sonic-db-cli, sonic-db-cli PING command tries to initialize the global database for all instances database starting. If all instance database-config.json are not ready yet. it will crash and generate core file. PR sonic-net/sonic-swss-common#701 only fix the crash and the process abortion. With this PR, many core files are still generated:
The following error are logged in the syslog
The following core files are generated
How I did it
In the database.sh, call function waitForAllInstanceDatabaseConfigJsonFilesReady to make sure all instance database-config.json are present before the command sonic-db-cli PING. This will avoid the database-config,json doesn't exist and cause errors and generate the core file.
How to verify it
With this change, after the image install and boot up, check and verify the syslog, the following lines should not be in the syslog and this related core file should not be seen.
