Hi developers,
My environment: MacPro OSX10.7 installed on a partition of 20 GByte; FreeSurfer v6 beta
During processing recon-all on 4 subjects in parallel using 4 terminal windows, the 20 GByte partition got full. This happened twice and I managed to trace down the offending stage in the pipeline: topology fixing, in particular the tool mris_topo_fixer. Most probably it went into an endless iteration loop generating so much output the disk got full.
Cheers, Ed
