/** * @file bug469 bug469 regression test case ("rwsplit counts every connection twice in master - counnection counts leak") * - use maxadmin command "show server server1" and check "Current no. of conns" and "Number of connections" - both should be 0 * - execute simple query against RWSplit * - use maxadmin command "show server server1" and check "Current no. of conns" (should be 0) and "Number of connections" (should be 1) */ /* Vilho Raatikka 2014-08-05 12:28:21 UTC Every connection is counted twice in master and decremented only once. As a result master seems always to have active connections after first connection is established.
