I encountered a compute error on an ATLAS native task that ran on my system for nearly two weeks before failing. Here's a summary of the failure:

Workunit: 231716588

Application version: ATLAS Simulation v3.01 (native_mt)

Client state: Compute error

Exit status: 195 (0x000000C3) EXIT_CHILD_FAILED

Host: ID 10873401

System: Linux Mint 22.1 (based on Ubuntu 22.04), CVMFS and Apptainer functional

Threads assigned: 5

Stderr shows this likely culprit:

mv: ‘ATLAS.root_0’ and ‘EVNT.44075481._002898.pool.root.1’ are the same file

This appears to crash the job early in its actual processing step, causing the wrapper to return an exit status of 195.

All CVMFS probes passed and the Apptainer container was loaded successfully from CVMFS. This seems to be an issue with the job script logic, likely in start_atlas.sh or its handling of the mv command near the start of execution.

Please let me know if you'd like additional logs or diagnostic output.

Thanks for all your hard work!
