Chris,

Yes, the ldm on sunset originally went down overnight at 03:28 CDT (0828
UTC). The machine was fine, but the ldm had crashed.  Somehow the
queue got corrupted I guess, from these log messages:

12704.439 prods per hour)

....

 
I remade the queue and started it back up at 1343 UTC (8:43 AM CDT)
and it ran until 15:51 or so, when it again died with a queue problem:

Aug 02 15:51:33 3Q:sunset pqexpire[539999]: assertion "status != 0" failed: 
file "pq.c", line 3993

Aug 02 16:00:07 5Q:sunset thelma[550505]: Disconnect
...

I just remade the queue again, and started it up. I'll try to keep
an eye on it, if it happens again I guess I'll need to increase the
queue size, or change the frequency at which pqexpire runs or
something..

Why do things like this always happen when I am on vacation? :O
Murphy's law I guess..

Sorry for the hassle.

Pete

Hi all,

Sunset's ldm took a dive again this morning.. It's running again
but who knows.. I am going to compile and install ldm 5.1.2 tonight
and see if that solves things.

Sorry for the hassles..

Pete
