Description of the bug

The final MultiQC step after running 3 analysis (AE/AS/MAE) either fails at low memory (48GB; 64GB with export_plots true) or runs for 18 hours ++ and is not able to finish (128GB - 400GB; after 18 hours, the memory used was 280GB and still climbing with export_plots false).

Research direction

Start by reproducing the final MultiQC step for the AE/AS/MAE analyses on Cambridge HPC, comparing the reported memory limits with export_plots enabled and disabled. Inspect the pipeline's final MultiQC entry point and collect command output and resource usage; done means identifying why memory keeps growing and confirming a fix or documented resource requirement.
