[lttng-dev] Issues running ust 2.1.0 as non root user

[David Goulet]

Hi Aaron,

You will have to provide the verbose logs of the session daemon. So,
quite simple, start in an other console the session daemon with your
user like so:

$ lttng-sessiond -vvv --verbose-consumer > /tmp/sessiond.log

And do the "lttng" commands again. It's going to be quite easier to
identify the problem.

A Fatal error of the session daemon, I suspect something is not right
with the installation or you are missing memory which I doubt :).

Thanks!
David

However, when I attempt to run UST as a normal user it seems that there is some issue with the session daemon that I am not quite understanding.  It looks like the permissions are correct on the executables in /usr/local/bin and such.  Here is the error that I see with the verbose flag on (not sure if this helps...)
