Any idea why I see an error when starting the linux app image: "Could not initialize OPC UA platform layer (error=0xffffffffffffffff)."
I can run other QT applications just fine.
This is on an ubuntu 22.04 image running inside a container with XFCE desktop and with "uaexpert-bin-linux-x86_64-1.7.1-540".
I tried enabling QT_PLUGINS_DEBUG=1 and no errors shown. I do see the splash screen start momentarily and disappear quickly.
Are there any dependencies that need to be installed that I'm missing?

Re: UaExpert Initialization Error on Linux
Hi,
the error during platformlayer initialization on Linux typically is caused by a mismatch between the number of file descriptors and the ULIMIT set by the operating system. Set the ULIMIT in your Ubuntu to 1024 and start the UaExpert again.
