Hi, I want to enable multiple(50) channel for the same session, below is my script doing the same. Single channel with the same script is working fine. But, when I tried to enable multiple channel for the same session it's giving me error.
Here is what I found 1) I have 50 channel in my db files and it's failing at 13th channel create command, below is the log ...12 channel creation successful Spawning a session daemon Warning: Could not get lock file /var/run/lttng/lttng-sessiond.lck, another instance is running. Error: Session daemon died (exit status 1) Spawning a session daemon Warning: Could not get lock file /var/run/lttng/lttng-sessiond.lck, another instance is running. Error: Session daemon died (exit status 1) 1 failed!
