We upgraded from MariaDB 5.5.34 to MariaDB 10.2.8 over the weekend. After the upgrade, we are seeing applications that use MySQL C++ Static Connector 1.0.6 fail to disconnect properly after a failed insert attempt. The client side thinks the application has closed, but the server still have the thread open, and a netstat shows it still open on the client side.
Is this a known issue? Is there a work around other than upgrading to MariaDB C++ connector? We had previously testing 10.1.18 and not seen this issue.
