Re: 20001107: LDM problem at University of Puerto Rico

Karli,

The problem appears to be a LDM queue management type problem that permits
the queue to grow on SGI machines. These problems have been fixed in the
latest release of the LDM 5.1.2.  There are binaries available for your
SGI platform.  The installation of the new release require the
commenting out the "exec pqexpire" in the ldmd.conf file and it
needs to have the queue rebuilt because it has a new struture. Hopefully
this will solve your problem, if it doesn't let us know.
