Limitations on subbuf_size / num_subbuf?</font>
<br>
<hr noshade>
<br>
<br>
<br><font size=3>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? <br>
<br>
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.<br>

Sorry for the noob question. I seem to be unable to define the total of
subbuf_size * num_subbuf higher than 4MB. I am getting ~30% discarded tracepoint
data.</font><font size=3> <br>

Any assistance would be greatly appreciated.</font><font size=3> <br>
