Could you please help? Any suggestion what should I check in this case as it is impacting our functionality.

If you are upgrading, we recommend that you upgrade to 3.x directly as that is the latest supported version. 2.31 is supported now but will be deprecated by the end of the year.

For this particular issue, 2.31.x and 3.x require a value greater than 0 for this property conductor.mysql.connection.pool.size.max.

Thanks @aravindanr for feedback. Can you please provide me 3.x version migration document?
