I see that UST debug tells us this: "libust[5389/5391]: Info: sessiond not accepting connections to local apps socket (in ust_listener_thread() at lttng-ust-comm.c:1221)" and also for global apps socket. So it means UST cannot talk to the session daemon. Are you UST and sessiond versions compatible ? The output of lttng-sessiond -vvv should help us understand why UST cannot connect to it.
