Linux Kernel version is 5.4.
Dockerfile provided as attachment.
So far we were not able to reproduce the error on our dev server. More logging on production servers ist sadly not possible.
As far as we can tell, they guacd service is usable perfectly fine. Segfault might be happening at the end of a connection.
If you need more information, feel free to ask. Will do my best to provide it.
