Dear Hantao
your problem is not a technical one. That error message
is issued when the PEANUT model cannot manage a physics case.
There is some probability that there is a real bug in the code.
Please send your input and all others possible additional files
(routines, data files, etc.) that are necessary to reproduce
your run.
In particular it is important to get also the last random seed (linked to
fort.2) left from a job aborting with that message
