Wayne,

This seems strange to me since "ldmadmin start" makes the same new_log call
as if "ldmadmin newlog" were called directly.  One way or the other, the
syslog process should get the HUP.  Tom thought you might be using a
Solaris system -- there are patches to syslog for several recent versions
to correct some nasty problems.  Can you tell me what version of Solaris
you're using (uname -a)?
