Hey, I am using the LTTng tracer (2.13.11, C-API, rotation=1s) to trace my ROS2 system (userspace only). Everything works just fine within my Docker Container (Ubuntu 24.04), but if I start the same procedure on the host itself (also Ubuntu 24.04), it does not create a TraceFile if to many tracepoints occur (speaking of roundabout 1500+ per second) (sometimes it malformed the tracefile, but I was not able to recreate that. If I remember correctly, Babeltrace2 threw an error that said that there was no metadata-file). I played around with some configurations (like increasing the buffer size from ~16kB to ~512kB or a less aggressive rotation), but the problem stayed.
Would be thankful for help. I guess I delivered to less information, please reach out what is interesting at this point, I am not sure about that :).
