Using a simple Gaussian-like Ansatz for the phase distribution of a theorywith a complex action, we show how the thimble integration for the averagephase factor can be plagued by a strong residual sign problem when the phase ofthe complex integration measure conspires with the constant phase of theintegrand along the thimble. This strong sign problem prohibits the accuratecomputation of the average phase factor when it becomes exponentially small,and causes a strong sensitivity to the parameters describing the phasedistribution.
