Lib-4171 : UNRECOVERABLE library error continued

Continuing the discussion from Lib-4171 : UNRECOVERABLE library error:

Hi CSM team,

Could I request further support on this suite please? I have encountered similar problem a few times in the last few weeks but I have managed to resolve the issues. In this last thread, the model failed at 10 months. I have now almost reached 5 years. So I think the model is stable enough to think this is not a science issue. I have had some issued with not being able to write to file because of disk quota on archer2. I have removed data from my work space so this should no longer be the issue. I have perturbed the restarts but this did not help. Much like in the previous discussion, I did the following:

  1. [env]PRINT_STATUS=PrStatus_Diag (Note: for debug only, revert back for actual run)
  2. [namelist:prnt_control]print_writers=1 (so output from all PEs is available).

The above settings caused the model to crash at start of timestep, but the model longer without them, so I reverted them.

I have since run it with PrStatus_Normal and [namelist:prnt_control]print_force_flush=.true. but this did not help either. Could I have some help trying to figure out what went wrong please?
