Hi, Thank for the quick response. Here is the missing data:
UST 2.6.32.12-205 (I had to make a tiny patch to make it compile) MemTotal: 24628852 kB lttng-ust-2.1.2 lttng-tools-2.1.1 lttng-modules-2.1.1 babeltrace-1.1.0 userspace-rcu-0.7.6 Which patch for 4MB?

Not at all a n00b question, but could you give some more info? what is your version of LTTng tools, are you using UST or kernel tracing? How much ram is on your system? Kernel version? I actually have the patched lttng that has standard subbuffer sizes of 4 mb, so I have not personnaly seen that problem. But the first thing I would do is upgrade to the latest stable.

I am getting ~30% discarded tracepoint data. Any assistance would be greatly appreciated.
