Pushover analysis error help

[CHANJAESEONG]

I'm trying to run pushover analysis and having this error
what is problem?

This means that you are experiencing convergence problems and analysis fails because it cannot satisfy the convergence test. From the messages, it looks like it happens post-peak at the descending portion of the pushover. Could you plot the pushover curve and see if the analysis continued until a reasonable displacement that is good for your purposes?
