Hi,
syslog is a facility to capture all logs generated. The logs are stored in /var/log, so open a Terminal, do "sudo su -" enter your password and enter "ls -rtl /var/log" to see what file was modified recently.
You can enter a "tail -f /var/log/system.log" (or any other logfile) to see the lines added there.
Likely some application is trying to tell you something.
