Current/Peak/Limit queue length shows, in order:
The number of connections currently in the queue
The largest number of connections that have been in the queue simultaneously
The maximum size of the connection queue
If the peak queue length is close to the limit, you may wish to increase the maximum connection queue size to avoid dropping connections under heavy load.
You can increase the connection queue size by:
Setting or changing the value of ConnQueueSize in the Magnus Editor of the Server Manager
Editing the ConnQueueSize directive in magnus.conf
