Please make sure that, when you test from a user account (not root), you
don't have a per-user sessiond running. If a user is not part of the
tracing group, it will spawn its own lttng-sessiond to trace its own
application. This would explain why you don't see anything in the root
sessiond debug log.

Also, there seems to be an issue with starting the 32-bit consumerd, as
far as I understand the logs. I'll let David look into this further.

Best regards,

Mathieu
