syslogd stopped

[Tim Kellers]

I found some OLD reports of this happening (back in 2001 or so), but I 
haven't seen anyone mention it.

On August 1st, my /var/log/maillog files started rolling over empty 
files, nightly, with only the "logfile turned over [date]" message in them.

Turns out, syslogd stopped running.  As soon as I restarted it, and 
grepped for it:

# ps -ax | grep syslog
48049  ??  Ss     0:00.02 /usr/sbin/syslogd -s

It began running and my /var/log/maillog file has entries once again.   
I'm a little baffled; does anyone have any idea what might be going on 
or could maybe point me to a resource I might have missed that discusses it?

Thanks

Tim
