Hey Neil
Hello,
When I create a session and try to capture some kernel traces I see the
following (first output from lttng-sessiond and then from the tracing session):
root@socfpga_cyclone5:~# lttng-sessiond -vvv
DEBUG3 [300/300]: Creating LTTng run directory: /var/run/lttng (in
create_lttng_rundir()
for future devs
looking for answers.
Thanks to you all.

Hey Neil,
I hope that this helps you!

Hello LTTng devs,
I am experiencing a strange problem with what I believe is corrupt metadata.
This is seen on v2.6.0 of LTTng.
If I try and parse recovered traces using Babeltrace, it fails with a
segmentation fault.

Unfortunately the results are not quite as I expect.
I have used LTTng previously, although I did not perform the kernel
