Don, Jonathan, thanks.

I think I finally figured how to do it. FWIW, here's what I do (caveat: this is on FreeBSD, applicability to other systems may vary):

  1. In nsd.tcl relevent section looks as follows: 

    ns_section ns/parameters
        ns_param serverlog      /var/log/aolserver/${server}.log
        ns_param pidfile        ${homedir}/log/nspid.${server}
        ns_param home           ${homedir}
        ns_param maxkeepalive   0
        ns_param maxbackup      5
        ns_param debug          ${debug}
        ns_param logroll        true

  2. I then add the following line to /etc/newsyslog.conf: 
    #logfilename [owner:group] mode count size when [ZJB] [/pid_file] [sig_num]
/var/log/aolserver/openacs-dev.log nsadmin:www 640 5 100 * B 
/usr/local/aolserver/log/nspid.openacs-dev 1

Now, AOLServer stores PID in nspid.$server file that is accessible by syslog, that is used to send signal 1 (SIGHUP) to the process with that ID.
