# Problem with Gaussian job

Hi Netters: I have the following problem and will appreciate your input!
I am performing a rather large CI calculation with the option density=curr.I
notice that the CI run appears to be converged, with a .rwf file about 1Gbyte in
size. Then it looks like the 2-electron density matrix is being calculated,
the .rwf file soars to 2Gbytes in size and the job crashes due to lack of
disk space. Why is the 2-electron density matrix being calculated and is there
anyway to avoid the creation of this large file? The end of the output file
is appended:
Thanks.
