Crash at startup due to connexion error

[Aegdesil]

When starting the container, I sometimes have this log:

This does not happen systematically, I suspect some race condition, maybe when the host is too slow to start the server ?
Restarting the container fixes the problem, but it is annoying to do regularly.

Is there a way to add a retry / longer timeout ?

@regebro Do you have any input here? The main change in the docker is an upgrade of unoserver.

[regebro]

It could be that it's slow to start, and that the code that improves the handling of what happens when LibreOffice isn't started then errors out.

"Binary URP bridge disposed" is strange, that sounds like Libreoffice crashed during the call. But the first error could be a timeout.

I'll look into if I can handle that better.

@regebro Thanks. Any updates?

[jimisola]

@regebro Any updates? Not sure if there is anything that I can change in the container image.

Merry Christmas!
