Chromium under QtWebEngine fails to start on some linux machines

[kanekotic]

Hello Chromium group excuse me for the post as probably this goes on the side of your group. I have an application that uses QtWebEngine 5.8, that underneath uses chromium 53. In some linux ubuntu machine (not all) i am facing some issues with Zigote communication. I post because i have seen similar issues being discussed in this forum but after followed their solutions I was unable to get it working. The error message is: 

LaunchProcess: failed to execvp:
/opt/myapp/libexec/QtWebEngineProcess
[7511:7511:0131/125813:FATAL:zygote_host_impl_linux.cc(182)] Check failed: ReceiveFixedMessage(fds[0], kZygoteBootMessage, sizeof(kZygoteBootMessage), &boot_pid). 

I have used strace to see if there was anything missing, but there was nothing more than this particular call fail that stand-up, also the stacktrace was not providing any useful inside (lots of unknown calls).  I will really appreciate if someone can point me on how to continue debugging this issue, or if there is a know solution.

thanks for reading and also thanks in advance for any help you can provide me.

chromium-dev might be more helpful, though have you searched for a QtWebEngine support group? It might be more appropriate.

By the way, if regular Chrome also fails on those systems, then you can file an issue (if you could not find one already) at crbug.com. If Chrome does not fail, then this usually means the issue is not in Chromium code and thus this group (or the more appropriate chromium-dev) is less likely to be helpful.

PhistucK done that already. I am posting here because as explained I have seen similar errors on your BB and this seems more a permission issue in linux systems related to using an embedded chromium browser.
