[MM3-users] Docker-mailman (performance?): "AH00894: declining URL", "AH01077: declining URL", "AH01105: NOT Closing connection", "AH01076: url: ... proxyname: (null) proxyport: 0"

I am using docker-mailman with GNU Mailman 3.2.0 (La Villa Strangiato).

Even I have had no complains previously, a list admin have received proxy errors a couple of days. Right after one occurrence I immediately looked at the logs and while I had no related errors in the log files in /var/log/mailman/web/{uwsgi,uwsgi-error,mailmanweb}.log, the Apache log often shows "AH00894: declining URL", "AH01077: declining URL", "AH01105: NOT Closing connection", "AH01076: url: ... proxyname: (null) proxyport: 0". The errors seems to go back a long time, also on previous versions of Mailman, but no one have complained about it until now.

Apache is version 2.4.6 on a RHEL 7 assuming Red Hat have backported any bugs about timeout previously know as hardcoded timeout of 30s etc.

I assume therefore that even Mailman did not indicate any errors, it may have been too slow to respond. The server does not seem to be slow at all. Is there a way I can enhance the performance of Mailman (Docker)?

I've asked about performance previously, but as I don't think my current question is related to REST, it's probably not related to https://lists.mailman3.org/archives/list/mailman-users@mailman3.org/thread/P....
