Carl,

I'm not aware of any patch problems like you described above. You didn't
mention what platform or OS. I'm assuming it's an HP. I would scan the
ldmd.log file for an unusual messages as well as the system log files. ie
/var/adm/messages or the log file for your system. There has to be some
error message produced.  Also, you can put the ldm in verbose mode by
sending it a USR2 signal. ie, kill -USR2 <ldmd.pid>  It's explained in
detail in the man page "man ldmd"  This should at least give us some clues
of the problem.  Also, did you try to send data to a downstream machine
that didn't have the patch?
