Will hyperkitty block mailman core from sending messages
I think this is strange, since the document says:
Updating the archives with posted messages is handled by a separate queue,
which allows for better memory management and prevents blocking the main
delivery processes while messages are archived. This also allows external
archivers to work in a separate process from the main Mailman delivery
processes.
but we found the messages are being blocked and then flushed out when we restarted the mailweb server (including hyperkitty server) and the reason why we restart the web server is about the memory usage which may related to this issue 1.
