Connection Pool – How to remove bad connection fro m pool?

[Jay Rajput]

I am using connection pool for my server mysqlpp::ConnectionPool class.  After
the MySQL restarts all my queries starts failing with following error:



Bad Query MySQL server has gone away



The problem is fixed when I restarted my server. Since the problem only
happens when the MySQL server is restarted, I believe that this happens
because of a bad connection in the connection pool.



How can I remove such connections from the pool? The release will just
return the connection.


Let me know if you have questions.


Thanks,

Jay
