Hello!
I use matlab R2015b for Win Server 2012 OS with local parpool. I have memory leaks on local workers when function inside parfor-loop generate warning. Also memory is not released after parfor-loop ends. Example:
x = rand(78, 1);
for j = 1:100
parfor i = 1:1000
[~, z] = kpsstest(x);
end
end
[~, z] = kpsstest(x) generates warning:
Warning: Test statistic #1 below tabulated critical values:
maximum p-value = 0.100 reported.
> In kpsstest>getStat (line 632)
In kpsstest (line 291)
Memory leaks on workers even when i use constructions:
warning('off', 'econ:kpsstest:StatTooSmall');
pctRunOnAll warning('off', 'econ:kpsstest:StatTooSmall')
Memory on start workers:

Memory on after executing code:

How to avoid memory leaks when function inside parfor generates warning?
Thank you.

This problem is the subject of this bug report. If you are able to upgrade to R2017a, that's the simplest workaround.
