Description:
This was changed to 128 (hard-coded) in 2009 but if you have a mysqld server running with a back_log setting of > 128 then the proxy's listen queue may be too small.

How to repeat:
Check for a setting to manage this value on the merlin agent. It does not exist.
Notice that mysqld has a setting back_log which allows this setting to be increased, and may need such a setting if a large number of clients may connect or connect in bursts.

Suggested fix:
Make the setting configurable in mysql-monitor-agent.ini
