HI, we are using WR6 RCPL16 baseline which has lttng-tools version v2.5.4. This version sometimes triggers SIGPIPE which our applications do not expect. There is a fix for this in newer versions of lttng-tools. We would like to patch the 2.5.4 version of lttng-tools to contain the fix for this issue. The upstream commit is: commit 8eadb073927f4184aeb659aace661ca2cf1cb40b Author: Jérémie Galarneau <jeremie.galarneau@efficios.com> Date: Wed Aug 5 21:26:34 2015 -0400 Fix: Use MSG_NOSIGNAL when calling sendmsg() Applications using the liblttng-ctl library are most probably not expecting the SIGPIPE signal which can be triggered by sendmsg() on a closed socket. Use the MSG_NOSIGNAL flag to handle such cases gracefully.
