My ldm (running on aeolus.ucsd.edu) keeps shutting down with the following message: 

        Feb 05 22:59:41 aeolus rpc.ldmd[4244]: Terminating process group
This is a complete shutdown. There are no ldm owned process left in the mix. I bring it back on-line and it will work for a while. Then it shuts down again with the same message.
I haven't a clue as to what is causing this. All sites feeding from aeolus should consider failing over to their alternate until this stops. I have a meeting to go to this evening (and six or seven hours worth of sleep) during which I won't be able to monitor the ldm. 

UPC:  Anybody there able to help me?

Larry

Larry...

In the last week, I've seen LDM mysteriously die on one Linux box.  I checked
system messages, and saw a logged "segmentation violation" from rpc.ldmd.
The same process was running on another Linux box with no problems, though
it wasn't processing exactly the same data.  Since "rpc.ldmd" is setuid
ROOT, I didn't get a core dump.

You might check your messages file (probably /var/adm/messages or
/var/log/messages) to see if something similar is logged.

Subject: Re: LDM Dies - aeolus downstream sites should fail over


Hi Larry,

I'm on aeolus.  I see the problem - an assertion about the state of the
product queue is regularly failing.  But, I don't yet see why this is
happening.

As per Larry's suggestion, sites feeding from aeolus should fail over
until further notice.
