[RegCNET] Model Crashes after regular interval

[IMRAN NADEEM]

Dear RegCNET Users,

I am running parallel version of RegCM3 on 4 processors. My model crashes
after every 90 days. The error log, for
3 crashes that occur at  90days , 180days and 270 days, is attached. I did
the same simulation on different machine using different
compiler but I got the same error. I am running at dx=10km with dt=30.

Thanks in advance
Imran
