I recall many years ago that unix tail is broken on large files, such that I wrote my own Perl tail for one job. You might want to look at tail for Perl Power Tools.

I would like to tail it for 10 minutes, restart the tail process for another 10 mintues, copying off tailfile to tailfile.chunk before writing to tailfile again
Please be more specific. Are you intending to skip (lose) 10 minutes of logfile? Do you just want to split the logfile into chunks at 10 minute intervals?

What is the fundamental problem you're trying to solve?
