[Radiance-general] rtrace: warning - ambient file "af" corrupted

[Daniel Uribe]

Greg,

Thank you very much for your help. Indeed, changing the number of cores to
-n 1 had no problems running the program. I will look for how to repair the
NFS lock manager of the operating system.

Thanks,

*Daniel Uribe*
