Description
(LTTng 2.8.0 lttng-tools a0f518a on Ubuntu 14.04.4, kernel 4.2.0-27-generic)
If you lttng load a session that requires too much memory for its buffers (e.g. the sub-buffers' total memory equals or exceeds the (virtual) machine's entire memory capacity), the system reboots (the session loaded was configured to run right away with one kernel channel). One would instead expect LTTng to report the memory allocation failure (followed by the release of any memory already allocated to the session being constructed).
