The files are over 2gb and I'm using gromacs 3.3 on a linux cluster with amd64's (is that enough info? let me know if you need more).

The only frame info I get is counting through the frames being checked until it gets to the last (corrupt) one at 4550.

Thanks for your help David. It's appreciated.
