Interesting. Rebuilt the entire LTTng set with the stable-1.8 releases (stable-0.9 for userspace-rcu) and I see the same behaviour:
When I hit ctrl-c in the daemon's shell, it doesn't respond and the CPU usage goes crazy (~90%). Can't sudo kill it (or lttng-runas) either.
What's strange is that if instead of:
$ lttng-sessiond -vvv 2>&1 | tee lttng-sessiond.2.log
I do:
$ lttng-sessiond 2>&1 | tee lttng-sessiond.3.log
Then ctrl-c terminates lttng-sessiond normally.
Using just the first level of verbosity:
$ lttng-sessiond -v 2>&1 | tee lttng-sessiond.4.log
also misbehaves. Somehow -v is responsible?
At this point, should I open a bug?
