Hey!

Since rebuilding today we’re experiencing a high number of server errors. It seems to be an nginx connection issue; in nginx/error.log I sometimes see bursts of `768 worker_connections are not enough` messages like this one:

`2021/06/02 10:42:21 [alert] 1143#1143: *28468 1768 worker_connections are not enough while connecting to upstream, client: (IP removed), server: _, request: "POST /message-bus/8fc08436f86f47479cf0dad3deb5c4dc/poll?dlp=t HTTP/1.1", upstream: "http://127.0.0.1:3000/message-bus/8fc08436f86f47479cf0dad3deb5c4dc/poll?dlp=t", host: "blenderartists.org", referrer: "https://blenderartists.org/t/convert-multiple-objects-to-single-mesh-with-vertex-grouping/489173/2"`

Any ideas how we can remedy this? We have plenty of CPU/memory available - could we increase the number of ‘worker connections’?
