Random 'cursor already closed' error

[jirihajek]

I got sometimes notified from the server about an error:

InterfaceError at /js/translate/modernmt/102793/
cursor already closed
Request Method: | POST
http://127.0.0.1:8090/js/translate/modernmt/102793/

I'm not sure about the exact repro-steps, but if anyone has any suggestion re. what to look for, I can try to get more information. Thanks!

I've seen several such reports, but we were unable to reproduce that in another environment, my wild guess is that something is terminating inactive TCP connections as this typically happens after Weblate does some possibly lengthy operation which does not involve database (accessing ModernMT in your case).

It might be a PostgreSQL configuration (which we ruled out in most cases) or something in the Docker networking (where my knowledge is close to zero, so I can't really help).

See WeblateOrg/docker#786, #3942, #4539

This issue looks like a support question. We try to answer these reasonably fast, but in case you are looking for faster resolution, please consider purchasing support subscription and make Weblate stronger.
