OOM Error on Archer Running UM8.4+UKCA

Description
Morning,
Since late March I have been running teh UM at version 8.4 with UKCA based on Luke Abraham's release job.
I had been initially limited to running the job in 8 hour chunks, getting 3 months & 10 days in those periods. On Friday I switched to 24 hour length jobs, as Luke had informed me that the issue that had prevented me running for more than 8 hours had been resolved.
However, both my jobs experienced a couple of OOM errors over the weekend causing them to crash out after between 13 and 15 hours.
I have resubmitted the jobs again this morning as 8 hour length jobs, and will add to the ticket if they experience an issue.
Thanks
James

If you rebuild the entire model now, you will pick up cce8.3.7 as the compiler - you won't need any special hand edits, however, you will need to ensure that the default cray-netcdf module is loaded, rather than cray-netdf/4.3.1.
If your model is running OK, there is no need to rebuild 'though.

This sounds like a problem we have seen with the Ceray cce8.2.1 complier - please tell us the jobid.
