Does this message indicate a significant problem with the model,
Or is it just a problem at a boundary layer that the model deals with properly?

Some models seem to spit this 65K times, others much less.

What does it mean?

Where are you seeing this? In yabsd.out? Is it in a model that crashed?

There was a small amount of discussion on this <a href="http://climateapps2.oucs.ox.ac.uk/cpdnboinc/forum_thread.php?id=187">thread</a>. It was in reference to a model that crashed.

Yes, in yabsd.out. No, the model appeared to complete and upload ok as result 665777.

There was no fatal error as in the referenced thread.

But the graphs displayed on the web page show no phase 3 results at all.

the yabsd.out for this run contains 65735 instances of

QT_POS : Mass weighted QT summed over level 17
was negative. WARNING: QT not conserved
2012 points were -ve and the scaling factor has been reset to 1

or similar, the points -ve ranges roughly from 1800 to 2569 and the leve is mostly 17 or 19.

Upload appeared to run smoothly from

Just wondering if the WARNING messages in yabsd.out and the missing Phase 3
graph on the web site are related.

Thanks,

You're missing a trickle, and it's the one with the graph data.

The servers are overloaded and/or their hds are full.

See <a href="http://www.climateprediction.net/board/viewtopic.php?t=2887"> this</a> 6 page thread for discussions / grips / moans etc. (Woe, WOE. Sorry, needed that).
