st: Bootstrap got stuck.

Hi there,
When I bootstrap a model, e.g zinb, in Stata, it often gets stuck. I think it is because in some iteration the model can't get fitted because when I let it run noisily it will show me "not concave" in the model fitting part. I try to set different seeds but it doesn't help. Is it because my model is not appropriate? Or is there anything else I can try to avoid this, such as setting initial values or saving some successful iterations and calculate the confidence interval manually? Any advice is appreciated. Thank you very much!
Haiyong
