Addon wiith uwsgi take all memory on hassio installation type

I write addon, which contain flask and uwsgi.

When I run addon on Supervised installation type, this work properly.
When I run this addon on hassio, this use all avaliable memory immediate after run.

Mem: 8068900K used, 57192K free, 3224K shrd, 4612K buff, 203200K cached

   72    67 root     S    34812   0%   1   0% uwsgi --ini uwsgi.ini

Whats happened? My mistake, or uwsgi and hassio incompatible?
