Ok, here they are (I hope one of them is correct): http://www.abusar.org/ftrace/ These ones I get after I saw the kernel message "Tracer stopped". http://www.abusar.org/ftrace/trace.txt.bz2 http://www.abusar.org/ftrace/trace2.txt.bz2 http://www.abusar.org/ftrace/trace3.txt.bz2 http://www.abusar.org/ftrace/trace4.txt.bz2 http://www.abusar.org/ftrace/trace5.txt.bz2 These ones were during a stall and after a nmap: http://www.abusar.org/ftrace/trace-stop.txt.bz2 http://www.abusar.org/ftrace/trace-stop2.txt.bz2 If none of these is valid, I will use monit to check for Tracer stopped and force the tracing to be disabled. --
