Python freeze on camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice())

See original GitHub issue

Hi all, I have a running software using pypylon and Basler acA USB cameras. Every now and then Python freezes on the command: camera = pylon.InstantCamera(pylon.TlFactory.GetInstance().CreateFirstDevice())

The annoying thing is that the command does not crash, python just freezes indefinitely. Opening the cameras in Pylon Viewer often result in that it freezes and “goes gray”

Has anybody else encountered similar issues? Is it possible to add an exception to that command, E.G. a 5-second timeout?

NVIDIA Jetson Xavier with JetPack 4.4 GNU/Linux (Ubuntu 18.04) 4.9.140-tegra aarch64

Thank you

Now we understood the issue better. there are 2 Workarounds:

reboot the system.
link the genicam cache directory to a directory that is not existing. e.g GENICAM_CACHE_V3_1=/tmp/tmp2
