# Stop syslogd.
# The client writes 8 message with 8192 to a localhost IPv6 UDP socket.
# Continue syslogd.
# The syslogd writes it into a file and through a pipe.
# The syslogd passes it via TCP to the loghost.
# The server receives the message on its TCP socket.
# Find the message in client, file, syslogd, server log.
# Check that 8 long UDP messages can be processed at once.
