[MM3-users] Unable to retrieve <800 members of Mailman list through Curl command

Hi Team,

       I am currently running Mailman 3 with version 3.3.1 and in built

postfix version 2.10.1-6 on RHEL 7.5 with PostgreSQL 11.7 version with default values. I am almost running 2000 lists with 128 GB RAM and 24 Cores on a single VM and on which all the mailman 3 components are running.

       It is observed for most of the lists having members more than

500 is displaying "Mailman REST API not available. Please restart Mailman Core" message on the postorius window and on running the CURL command over REST API of Mailman it is reaching the time limit 30 seconds and showing the below error.

*curl: (52) Empty reply from serverNo JSON object could be decoded*

       The same behavior is observed on browsing the held messages for

few lists either through the browser or through CURL and REST API.

       How to resolve this issue ? What other details I can provide to

make you get an idea ?

Thanks & Regards, Shashi Kanth.K 9052671936
