The default error page includes a stack trace in debug mode and a one-line description of the error (e.g. “500: Internal Server Error”) otherwise. To produce a custom error open files”-Error). To raise this limit (setting it to 50000 for example) you can use the ulimit command, modify /etc/security/limits.conf or set minfds in your supervisord config. 36 Chapter 6. DocumentationTornado
