MySQL: Got an error reading communication packets

[enumag]

I wanted to try pootle using this but it doesn't work for me. When I run docker-compose up I get these errors after a short while and pootle doesn't work:

mysql_1   | 2018-04-22 10:32:54 140687299213056 [Warning] Aborted connection 8 to db: 'pootle_db' user: 'pootle' host: '172.18.0.4' (Got an error reading communication packets)

Any idea how to fix it?

Ok maybe it't not an issue with mysql. It seems that the pootle service is unable to start. I improved supervisord.conf to see more errors and got this:

pootle_1  | 2018-04-22 11:02:40,033 INFO spawned: 'pootle' with pid 24

pootle_1  | 2018-04-22 11:02:40,344 INFO exited: pootle (exit status 0; not expected)

That Can't import flup.server.fcgi_fork line bothers me. I'm guessing that's the real issue.

For whoever is struggling with this in 2019 - the solution is to install flup 1.0.2 with
pip install flup==1.0.2
