I have 2015a. Never had problems with "close" or "close all" in the last two decades. What gives? I had 20 figures open from a plotting function. I turned off tiling, just let them plot naturally one on top of another. Still no joy. Completely baffled at this "new" behavior. Output is listed below.
>> close all
Error using unique
Too many input arguments.
Error in ismemberCismemberClassTypes (line 376)
[uA,~,icA] = unique(a(:),'sorted');
Error in ismemberRismemberR2012a (line 165)
lia = ismemberClassTypes(a,b);
Error in ismember (line 57)
lia = ismemberR2012a(A,B);
Error in setdiffRsetdiffR2012a (line 193)
logUA = ~(ismember(a,b));
Error in setdiff (line 83)
[varargout{1:nlhs}] = setdiffR2012a(varargin{:});
Error in close>safegetchildren (line 338)
Error in close (line 132)

What does this command show? If it shows unique.m functions other than those included in MathWorks products, remove the directories containing them from the MATLAB path, rename them, or remove them.
which -all unique

Thanks, it worked. I am, however, puzzled as to why this never happened before. "unique" is a bad choice for a function name for several syntactical reasons but there are plenty of such examples.
