Hi Hubert,

Quite hard to figure out what's going on with just this information.

There's nothing else in the connection pool configuration, other than what you already pasted here?

Could you please turn on the general log in the server (https://dev.mysql.com/doc/refman/8.0/en/query-log.html) and watch for "Connect" and "Quit" events while this process is running?

This seems to be a bug and it may related to how pooled connections are handled. Is there any way for you to run this without using the connection pool?

BTW, have you tried profiling the running process? It could help identifying the real source of the problem.

Please provide any other information you could think of that could be relevant us.

I'll keep in touch if I find something else in the meantime.
