[lttng-dev] [bug]session create failed

[Lingyu Zhu]

Hello,
Sorry for being away a few days. My thesis opening proposal is hiting the
deadline, which happens to be same date for GSoC. Now I can be fully
devoted to lttng and compose my GSoC proposal.

Anyway, I may have found a bug.I'm not very sure. Here is my log:

===================================================

======================================================

These command is issued right after my machine is booted. And if I directly
switch to root and create a seesion, everything is normal. So I guess I may
have come across a bug.
Any comment?
