Web application crash

Running web application crash some time with the following error message:
App is shutting down: Server Error #24. See http://docs.realsoftware.com/index.php/SocketCore for details.
Link also not opening

Web App type : Standalone 64bit
Xojo : Version 2019 Release 2
Server : uname - a -> Linux 4.19.0-5-amd64 #1 SMP Debian 4.19.37-5+deb10u1 (2019-07-19) x86_64 GNU/Linux

The correct link is http://documentation.xojo.com/api/networking/socketcore.html#socketcore-error which will lead you to http://www.ioplex.com/~miallen/errcmp.html where you will see that the OS is complaining of “Too many open files”.

You should file a feedback case about the link in the error message.
