Dear Jeremy and all,

Recently we have  upgraded Redhat 9.0 (kernel 2.4.20-6smp) on out office computers.

I have tried to run the simualtion with different version of RegCM on those mechine but they generate floating point exception error all the time. 

I have tried all the options i can think of... like decreaing the time step, changing the domain size, different the driving data, different convection scheme etc but with no success. 

Model crashes imidately or after few time step.

I am running the model in different computer with Linux Mandrike 10 with same model configuration.

Is this problem related with linux version or something else?

I have attched two messages of simulation for trouble shooting.  

Any help/ suggestion will be appriciated   

Best Reagards

Jagadish
