Strange Halting at Half Total Iterations

[finzeo]

Edit: The issue has reappeared, even with the temporary solution I mentioned in the previous message. The problem is that inconsistently, in some runs, a .lock file is generated when writing to disk (either for checkpoint or post-processing), and the run gets blocked. This occurs when running within an HPC cluster.

The solution we found (which is a workaround) is to force sequential (non-parallel) writing. This can be done from the GUI: Performance settings > Input/output > Read/write method: Standard I/O, serial.

I understand that for heavy cases where a lot of disk writing is done, this could be a time constraint, but generally, there shouldn't be a problem.
