Platforms interpret the value of MAX_CONNECTION_QUEUE_LENGTH differently. Some platforms interpret |
| |
the value literally, while others multiply a fudge factor. When the server is under |
| |
stress from multiple clients with multiple requests, toggling this number may prevent clients from |
| |
being dropped. Instead of hard coding the value, we allow an environment variable to be set which |
| |
specifies a number greater than the maximum concurrent client connections possible. If this environment |
| |
var is not specified, then MAX_CONNECTION_QUEUE_LENGTH = 15. |
