UaExpert Initialization Error on Linux

[beckerben]

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?

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.

Brilliant, that was it, thank you!
