Hi, I have a recurring problem of tools like babeltrace and TraceCompass exiting because of an allocation failure.
For example running babeltrace on a captured trace leads to babeltrace processing some events, and then exiting with: GLib-ERROR **: gmem.c:168: failed to allocate 17179869184 bytes This sounds like a corrupted trace file to me. Or maybe a version or format mismatch? In case it helps, babeltrace's backtrace at that point is attached to the mail. I'm using lttng-relayd 2.9.4 on the host, and lttng 2.9.4 on an i.MX25 device. Babeltrace is at version 1.5.1. The same problem can be seen when not using lttng-relayd. I've also seen other problems like "[error] Event id 3336003216 is outside range." lttng-sessiond shows no warnings or errors during recording, and neither does lttng start or stop - not even lost events. Any idea how the trace file got corrupted and how I can record traces without corruption in the future?
