This does not look out of the ordinary.

Since pqbinstats is part of the LDM process group, it terminating
abnormally would cause the LDM to exit.  This is what is happeing in
the following log messages:

Super, thanks!

The cause of the exit was most likely pqbinstats dumping core.  Why
this happened, I can't tell since the core file appears to be gone now.

Later...

If you still think it is a good idea to look at the core file, it is ~ldm/logs
(not sure why you couldn't find it before?)


Thanks,
