Is there any way to limit the resolution time to lsqnonlin?

I have a "while" cycle that execute a optimization using lsqnonlin, the problem is that in some iterations it can't solve the system, showing the following:
"Warning: Reached the limit on the maximum number of intervals in use. Approximate bound on error is 3.1e+01. The integral may not exist, or it may be difficult to approximate numerically to the requested accuracy."
It sometimes happen by hours, so I want to know if is there any way to limit the resolution time to lsqnonlin or a way to follow with the next iteration? (I do not care if I do not get a solution for this iteration)

You can use the 'OutputFcn' option to send a stop signal. lsqnonlin will stop when the Output Function returns a value of 1.
