Subject: [ltt-dev] Cannot destroy trace

Hi all,

I have modified the original lttng kernel patch to fit my RT-linux patched
2.6.30 kernel. And IMHO the kernel now works fine.
Everything seems OK until I run "lttctl -D trace1", the process became
"blocking like"(I am not sure if it is blocked).
The last msg printed on the screen is "lttctl: Destroying trace".
Then I added some debug message into the liblttctl.c file. As a result, the
process was "blocked" while executing
*write(fd, op, strlen(op))* in function *lttctl_sendop()*.

Any advice? Thanks in advance.

*regards,
Jerome*
