This error is a general prompt. If you suspect that the connection cannot be released, you might consider adding some details to support this. At least from the error prompt and the corresponding solutions found online, it could be anything. :joy:

These parameters still have no effect when placed inside, but I tested MySQL and it works fine. The TiDB connection gets maxed out.

Was it finally resolved? I’m encountering the same situation here, where the connections suddenly get maxed out.
