You've hit a 2Gbyte limit on disk I/O. Possible solutions might include
a) ensure the program is built with large file support, and that the
kernel/run time support this.
b) run instead on a 64-bit machine
The latest version of Molpro prints a more informative diagnostic, and is
not held up at the 16Gbyte disk limit for atomic-orbital integrals, but this
isn't the issue with this problem, I believe.
