Hi All,
I'm using 2.6.0 and see following issue:
On a multisession setup with relayd, Destroying one session is showing
errors on the console and tracing of all the sessions is stopped.
steps to recreate are as follows
1) Create multiple sessions with relayd. (in below logs i have created 2
sessions)
2) Destroy one session and then tracing on all the sessions stops
(Have not check this with single session, could be happening with single
session also)
logs
---------
node-a # lttng list
Available tracing sessions:
1) mys5 (tcp4://128.0.0.4:5342/ [data: 5343]) [active]
Trace path: tcp4://128.0.0.4:5342/ [data: 5343]
Live timer interval (usec): 2000000
2) mysession (tcp4://128.0.0.4:5342/ [data: 5343]) [active]
Trace path: tcp4://128.0.0.4:5342/ [data: 5343]
Live timer interval (usec): 2000000
Use lttng list <session_name> for more details
