[Wrf-users] problem running real.exe

Hi Sam,

I'm guessing your using HECToR? If so, you need to put lib.cat somewhere 
in /work so that the running job can access it - set the NLSPATH env. 
variable to point to it in your job script. I can't remember how I found 
where lib.cat was originally but maybe google will help. If not, contact 
me and I'll give you my copy.

However, all the above will do is give you a more precise error message. 
I've only ever came across this error from running WRF compiled in 
OpenMP+MPI mode with the PGI compiler. Despite going in and increasing 
the length of the buffer being written to I couldn't fix the error. In 
the end I got around it by using the Pathscale compiler instead.

Hope this helps,

Andy.
