Hi John,

Thanks!  This is helpful.  I see a few things going on:

Looks like you're trying to run pqsurf without a pqsurf queue.  The LDM
is coded to exit when one of its children exits.   Below we can see that
the parent rpc.ldmd, PID #179, has decided to exit, thus terminating the
whole process group.

I wonder about these.  I don't know if this is a separate problem or if
it's related to the termination of the process group, although I suspect
the latter.  I would try an ldmping to these sites to ensure that the
RPC call won't time out.

So, please fix the pqsurf problem and let me know what happens. 

This sounds different than when you said the LDM would run for a few
hours and then quit.   Perhaps something else is also going on...
