[soffice.bin] <defunct> #176

Closed L3o-pold closed 3 years ago

L3o-pold commented 4 years ago

I have a lot of defunct processes using the libreoffice builder. Even upgrading to the latest version (libreoffice 6.4.0.3)

Do you have any idea to fix this?

An important note is that I removed the lock and generate a random -env:UserInstallation path. But if I remove those hacks, I still have one defunct process.

We found a workaround to our issue. Using https://github.com/Yelp/dumb-init in our Docker image.

Ah yes, thanks for the information. You indeed need a proper init process to handle the dying processes. In your listing, python was being used as init. You must be using a very bare docker image, right?

L3o-pold commented 3 years ago

Based on python official images. I think it can occurs with any docker image that have python as main process.
