By the way, the consecutive seds in the pipeline can be simplified: sed 's/,/:/3 ; s/,/:/3'.
That'll save some time in context switches and copying data in and out of kernel/userland buffers.

Also, it seems GNU sort can handle this situation, by automatically creating tmp files during the sorting process. I'm assuming you're not on Linux. If so, and if you are using GNU sort, you should paste the exact error message.
