[Freesurfer] tksurfer - failed to calloc

Hi Surfers, I get the following error when I use tksurfer for one of our subjects: znzTAGskip: tag=1830834290, failed to calloc 1834378240 bytes! To clarify, this error is only limited to freesurfer version 6.0 and 7. But version 5.3 works fine with the same subject. Regards
