It seems likely that openssl hasn't been compiled with large-file support.
Not so uncommon with RH5.

Can you send the output to stdout and redirect?  Or if that fails then
send to stdout and filter via "dd" to write to the file.  Now at this
point openssl is only writing to a pipe and won't hit the 2G limit.
