The problem comes from your data file. I guess you write your numbers
with a fixed field length, and you simply reach the maximum length for
node numbers > 9999. For example, you have

17661    2  100    6    3 9998 2542 9999
17662    2  100    6    3 9999 254410000

Gmsh cannot read the second line, since it expects 3 node numbers (9999
2544 and 10000) and only sees 2 numbers (9999 and 254410000)...
