Solver error output in topology optimization (TOSCA on Abaqus)

Hi, I need the help of this community one more time.

I'm running a topology optimization on a linux cluster, 

I get this error message in the TOSCA.out file:

Solver output file was not found: /state/partition1/marta/451938.rng.wfw.wtb.tue/to_results/Opt-Process-1-Job.msg

Where "to_results" is the output folder and "/state/partition1/marta/451938.rng.wfw.wtb.tue" is the cluster path.

This is quite strange because the to_results directory is created during the process, so I don't know how to fix it.

Is anybody familiar with this error?
