Good Morning,

I have a job failing at coupled after a month

/work/n02/n02/jgrist02/cylc-run/u-da510/log/job/19500401T0000Z/coupled/01/job.err

(I have a similar post that indicates it might be related to not starting with a reconfigured UM 10.6 start file? But can’t find the solution)

With many thanks for any help in resolving this.

Jeremy

Could you help find the issue? many thanks, Jeremy snippet from /work/n02/n02/jgrist02/cylc-run/u-da314/log/job/19501001T0000Z/coupled/04/job.err: [126] exceptions: An non-exception application exit occured.
