Hi David,

OK.

I would not think that a reboot would helped unless something was
very wrong.

>It seems to be ok after I upgrade the LDM software.

I looked at the assertion error you reported:

Dec 08 05:24:22 rcz006 atm[13870]: assertion "n > 0" failed: file "pq.c", line 
2187

and see that it is in a check in a routine that takes the log of a number:

/* return floor(log4(n)) */
static int
log4(size_t n)
{
    assert(n > 0);
    return (int)(log(n + 0.5)/log(4.0));
}

Very strange indeed...  I will talk to Steve Emmerson (our LDM guru)
about what could have caused this error when he gets back to the office
(he is attending the AGU meeting currently).

>Regards

Cheers,

Tom Yoksas
