Hi
When I have ran two or more Freesurfer instance in pc with one geforce gtx 460. I usually get a abort or memory corruption when running two or more Freesurfer instance. I usually get trouble when two ore more Freesurfer instance is in autocon3 phase of the recon-all protocol.
Cheers Knut J
Try running only one GPU-assisted recon-all

It work fine with just one GPU-assisted recon-all.

Sorry, I messed up earlier, and didn't send my reply to the list..... your experience makes sense, since the Freesurfer programs make no attempt to share the GPU beyond that which the driver imposes. Running out of memory (particularly on a low end card like yours) would not be surprising when running three recon-alls at once.
