The issue appears to be caused by failure to obtain peudo-random numbers 
with getrandom(), so there may be something missing on your system in 
that area. Running lttng-sessiond under strace may help figure out 
exactly how this is failing.

Also providing the output of lttng-sessiond in verbose mode would be 
helpful (lttng-sessiond -vvv).

Thanks,

Mathieu
