Hi Sebastian,
take a look at your surfaces. If it's using that much memory something is probably dramatically wrong. Most likely either the cerebellum is attached or the skull.
Aargh, yeah I have some skull and all of the cerebellum attached to lh.orig. Well I am trying my best in skullstripping now (hard, as I only have highly inhomogenous surface coil for send and receive scans). I am using the monkey skullstripping guide posted recently by Florent (thanks). About the cerebellum I will try my cutting skills at the wm.mgz...

Will do that. A question though, the machine has 4GB Ram and 4GB swap space and addressable space somewhere in the low TB, why is it that it breaks, even if it allocates too_much_memoryTM?

Hi All,
some more details to the segfault. The critical program is mris_fix_topology, which allocates around 3.7GB of memory and hogs the CPU for at least an hour, then while holding around 3.6GB goes into D state (as seen by top) and then after some time segfaults with the error code 4. Error code 4 most likely means (on Linux x86_64) user_mode page_not_found on read. If I can help debug this I would be happy to.
