. Too Many Open Sockets Issue
Sometimes our clients will get a “too many open sockets (FD_SETSIZE=2048 reached)” log error on very busy servers. This error occurs when you try to open more than 2048 socket connections for an instance of Iguana.
Run the socket diagnostic command to check socket usage:
Code Block http://localhost:<Iguana port number>/socket_diagnostic.html
Adjust the IGUANA_WEB_SOCKET_IDLE_TIMEOUT_SECONDS system variable to a lower value (default is 120 seconds) – you can set it as low as one second.
