Could you do a search for this file and make sure it exist ?<br>
<br>
Also it might be a good idea to uninstall everything (lttng-ust,
lttng-tools, lttng-modules) make sure that you install the same
version (stable 2.8 from git if you can) for all three.<br>
<br>
I also requested access board on <a class="moz-txt-link-freetext" href="http://open-estuary.org/">http://open-estuary.org/</a> to test it
myself.<br>
<br>
Cheers<br>

Yes ,I tried,reboot the board,and "ps -A|grep lttng"
,here is no lttng session.<br>
after " lttng create mysession ",there is an error "
Error: Could not get lock file
/var/run/lttng/lttng-sessiond.lck, another instance
is running."<br>
I used "2.8.0-rc1" version this time. Same problem.<br>
<br>
Logs:<br>
<br>
-bash-4.3# ps -A|grep lttng<br>
-bash-4.3# lttng create mysession<br>
