<p>Hi,</p>
<p> </p>
<p>In my code I create and destroy during one run a lot of MPIAIJ matrices and it seems that not all memory is freed when I destroy the matrices. Moreover, it looks like the amount of “disappearing” memory increases with the number of processes. I am not so sure if I am doing something wrong or if it is really a memory leak. I have attached a simple reproducer.</p>
<p> </p>
<p>Best,</p>
<p>Marius</p>
