Hi Shahriyar, I have not made much progress on this as all my efforts ended without any issues. I have tried on many OSs(except CentOS) but not seeing the crash at my end. I'll give it a try today on CentOS and will comeback. thanks, Umesh

Hi Shahriyar and Umesh, The issue is in 3rd party library `protobuf`. To fix this, I have to know if mysqlsh on centos is using shared protobuf library or static one. Could you send me printout from shared object dependecies of mysqlsh, please? Find `mysqlsh` path, using: $ which mysqlsh and get shared object dependecies by: $ ldd `which mysqlsh` or $ ldd /path/to/mysqlsh If your `mysqlsh` depends on protobuf dynamic library, please upgrade `protobuf` library on your OS. Best regards, Krzysztof

Posted by developer: Hi Shahriyar, You found bug in MySQL Connector/Python driver and thank you for the bug report. Issue with `mysql-connector-python-8.0.4-0.1.dmr.el7.x86_64` is that Connector/Python use dynamic loaded `/usr/lib64/python2.7/site-packages/_mysqlxpb.so` which use `protobuf` version with this bug https://github.com/google/protobuf/pull/1062. Reported bug will be moved to MySQL Connector/Python team. `import mysqlx` imports Connector/Python library module which is not supported to be used with MySQL Shell. You should use `mysqlx` module from `mysqlsh` package which is supported by MySQL Shell, i.e. `from mysqlsh import mysqlx` instead of `import mysqlx`. $ mysqlsh root@localhost --py --execute "from mysqlsh import mysqlx" To sum up. Please use `from mysqlsh import mysqlx`. Best regards, Krzysztof

Posted by developer: Issue can no longer be reproduced, please reopen if you can still repeat with the latest version. Furthermore, the command to import the mysqlx module in the shell should be: from mysqlsh import mysqlx Directly importing mysqlx is not supported in the shell, only in standalone Python interpreters.
