a strange error as writing restart files

[jyangdas@gmail_com]

Hi,I met a strange error when I port CCSM3 to the cluster of University of Chicago. I can well conifgure, build and run the model, but the model blow up just one month before STOP_N.For example, if I want to run 3 months, the model blows up at 2nd month. It likely results from the step of writing restart files. I know that CCSM3 is not the model suggested yet, however, I will be very grateful if you can give me some suggestions. The error message is like this:**********************************************************nstep, te 7246 3343331092.90397 -4.97626708282365
