Re: 20020803: several messages from Gilbert re: LDM 5.2 crashing

Gilbert,

I was able to get LDM 5.2 to crash on Linux 7.1 system, didn't crash on a
Solaris 5.9 system though.  It appears that the problem is pqsurf.  So
have you tried running the system w/o pqsurf? and then trying to run 5.2
with 5.1.4 pqsurf?

Let me know the results.

Robb...
