I don't think it is just a specific name. It is a combination of several different things...like name, date of birth, nationality, etc.,
If there is a partial match with someone on FBI list, then the automated system won't clear it, and it is assigned to a person to manualy clear it. It will stay pending..till that person gets around to doing his/her work.
It is not just a terrorist watch list names, or muslim names. If your personal information matches any criminal known to FBI...then your file could get stuck in the name check.
