[Pkg-mailman-hackers] Bug#1014037: mailman3-web: Possible memory leak: uwsgi OOMs after a few weeks

[Michael Tremer]

I can also confirm this running mailman3-web in Apache. Usually it only takes a few days. I have attached a graph to illustrate the growth.

I am using this to launch it:

  WSGIDaemonProcess mailman3 processes=1 threads=8 display-name=%{GROUP} home=/usr/share/mailman3-web

Adding a "maximum-requests=1” does not help at all. Swapping processes and threads does not bring any change either.

I have no idea what to look for but I am happy to investigate if you have any ideas.
