I don't have the detailed explanation handy, but you broke the system's
link with the file. From that point on, syslogd can't write to it (you
actually create a new file as far as the system is concerned; I believe
the old file is still being updated, but you can't see it anymore). You
can SIGHUP syslogd to reconnect to the output log file (see the syslogd
man page under SIGNALS).

I usually just 'echo -n < /dev/null > filename'. This overwrites without
breaking the syslogd connection.
