Hi All,
I'm using 2.4.1 and all of a sudden i see relayd getting coredumped.
I see that its backtrace(shown below) is similar to that of
https://bugs.lttng.org/issues/722 [SIGABRT using lttng-relayd (assertion

I'm not sure what is the trigger for this, but it happens randomly.
Can anyone tell me if these issues are same?
Also i see the fix is targeted for 2.6
