Possible invalid discarded events count
From Issue #1110:
Then, when running as root, the test will abort if the problem is triggered: lttng create lttng enable-channel -u chan_ust lttng enable-channel -k chan_kernel lttng add-context -u -t vpid -t ip -t procname -t vtid -c chan_ust lttng enable-event -u -a -c chan_ust lttng enable-event -k -c chan_kernel --syscall --all lttng start LD_PRELOAD=liblttng-ust-dl.so:liblttng-ust-fork.so:liblttng-ust-fd.so ./fork12 After forcibly stopping the test (^C), errors are reported and events could be miscounted when issuing lttng stop: [warning] 9223372037047268318 events discarded, please refer to the documentation on channel configuration.
Possible source of problem is that a negative is returned somewhere. Either by kernel or ust trace.
