John,

Currently the GeoTIFF driver does not open and close files dynamically.  If
you are on Unix or Linux I would suggest you look into the limit or ulimit
commands to control the maximum number of open files supported in a session.
It can usually be increased.

If that fails, you will need to find some other approach to managing the number
of open files yourself.
