Hi.
I have a ion channel (A_BC) that when I used it as a mechanism in my hoc file, this error comes:

exp(702.138) out of range, returning exp(700)
A math function was called that returned an out of range value
errno=34 during call to mechanism A_BC
nrniv: errno set during calculation of states
near line 60
{run()}
^

What’s the problem by this error?and how should I do to solve it?

Numeric overflow. Suggest you check for the usual suspects--divide by 0, exponents that
blow up, etc.. modlunit is good for tracking down errors. Can't tell you anything more without
seeing source code.
