I see you have GC logging enabled, what do you see in "E:\topupfix\GC.log"? Are you in the midst of a full gc? Also, while the response is hanging (i.e. during the 2-3 minute window) take some thread dumps (two or three is sufficient). Check them to see what is happening in the application during that time period.
