[lttng-dev] UST Create Channel Failed, Why?

[Dilong Zheng]

Hi all,


While trying to enable UST events, I get the following error message:


Error: Event mitel:sem_wait_entry: UST create channel failed (channel channel0, session mcdUST3)


When I type: lttng list -u I am able to see a list of all my UST tracepoints.

Could someone please provide some insight as to why this error is appearing and steps I could take to fix this error. Thanks.
