# The syslogd is started with reduced file descriptor limits.
# The syslogd config contains more log files than possible.
# The client writes a message to Sys::Syslog native method.
# The syslogd writes it into a file and through a pipe.
# The syslogd passes it via UDP to the loghost.
# The server receives the message on its UDP socket.
# Find the message in client, file, pipe, syslogd, server log.
# Check the error messages and multiple log file content.
# Check that the error messages appear on the console.
