This isn't an OpenVPN problem, directly. It appears you have a client connect script, or are storing connection information in temp files. You can increase the maximum allowed open files in Fedora (you'll have to research that yourself). Alternatively, stop storing connection data in a temp file for new connections. OpenVPN, by itself, does not create these temporary files.
