I get the fault but can not replicate the issue, without a debug log it will be impossible to just guess what the issue is.
it doesn't even leave the image log because the decoder works, only oscam crashes, the only thing I can see is that in oscam status it tells me: "Errno 111" and on the webif at the bottom it says "POLLERR" in red
i think doing a downgrade of oscam maybe it will work.
