[Freesurfer] qcache error

Dear Freesurfer experts,

I have got a problem with the qcache function. I have already runned 150 subjects with the recon-all command. Before i can work with the statistical program qdec i have to smooth the subjects. I want to smooth them with the command: recon-all -s <subject> -qcache. The command start to run but finished with errors. A overview of the terminal output is attached to this email in JPEG format. What is the problem in this case?

further information about freesurfer version:

recon-all -version: Id: recon-all, v 1.373 2011/03/15 00:43:47 mreuter Exp $

We run FreeSurfer-Linux-centos5_x86_64-dev-201110315 under Debian Squeeze.

Thanks a lot,

Stan van den Berg
