I'm having a problem with nls: it iterates the correct number of times according to nls.control, but mis-reports how many iterations have occured! It converges on the correct parameter values, but doesn't stop and report them until it's done all its iterations. Then it reports as an error that it's stopped becaue it's done all its iterations. Not sure what's going on....
But I suspect you have more idea than we do. Please read the section on BUGS in the FAQ and send us a reproducible example. (The iteration count is a *limit*, so sounds as if nls is not converging if it does that number of iterations.)
