Model long run crashed

Reported by: fcentoni Owned by: annette
Component: UKCA Keywords:
Cc: Platform: ARCHER
UM Version: 7.3



I have been running without any problem two jobs (xkzra,xkzrb) (10 years run lenght) since 2 days ago.
At some point, in one of the last run, the model crashed giving me this error (see output files xkzra004.xkzra.d15027.t220300.leave

UM ERROR (Model aborting) :
 Routine generating error: U_MODEL
 Error code:  1
 Error message:
DUMPCTL : Fail to open output dump - may already exist

Could you help me out to fix that (there only 2 years to go).

Many thanks.

Hi Federico,

Do you know what the problem was or what fixed it?

Hi Annette,

it turned out that the model had produced a huge amount of dump files causing the run to crash.
So I basically manually deleted the most part of the dump files and restarted the run using of the last start dump available. Then it got back running until the end.

However, I tried to restart the same base job (I made a copy of the original so now it called 'xkjti') running the same code, same ancillaries and it turned that the model crashes during running after 15 mins. It gives me an error I am not familiar with at all. As you can read in the .leave file, this error is:

UM ERROR (Model aborting) :
 Routine generating error: U_MODEL

I would need to get my base job running as soon as possible so your feeback would be much appreciated.

Many thanks.

I meant that I tried to rerun the same job (10 years run length) now called 'xkjti'.

I looked at this last week but there was no job 'xkjti' in the UMUI, either because it's not there or you've made it hidden.
