#2321 closed help (fixed)

postproc jobs lag substantially behind model run cycles

Reported by: marcus Owned by: um_support
Component: Archiving Keywords: postproc
Cc: Platform: NEXCS
UM Version: 10.6


Hi, my current suites u-ar155, u-ar286 and u-ar292 seem to be suffering from a postproc run delay. I have checked MONSooN Yammer messages etc but found no downtime or other reasons for delayed copying of model output to MASS, assuming that this would be the most likely possibility for a delay.
I am frequently confused by gcylc showing consistently running status, qstat on xcs showing R status, but then in reality the jobs seem to be no longer running? Is this possibly related to earlier disk issues with the cylc server, mentioned e.g. in ticket #2310?
Many thanks,

Hi, postproc for u-ar286 has now failed with the following error, relating to um-pumf, that I do not quite understand:

Please what could I do to fix this?

Hi Marcus,

The file


is corrupted: if you look at it in xconv you get the error "WGDOS data header record mismatch". This is probably why pumf fails. I think this is related to the "Updraught maas flux" field, though my analysis tools also fail on the file.

So you should check your run processes which produced this file and see if any errors were reported.

Thank you, Willie. I am not sure how this could have happened. I have stopped this run now and will continue from an earlier dump when I resume this experiment.
Many thanks, Marcus
