Re: problems to use lttng

Hi there,

Lttng 0.6.80 is properly installed, together with lttv 0.8.81. I'm still
losing all events (dmesg output attached).
This is what lttv tells:

# lttv -m textDump -t /tmp/trace -d -v

** (process:5067): CRITICAL **: cannot open trace /tmp/trace
** (process:5067): DEBUG: Option verbose hook called
** INFO: Logging set to include INFO level messages
** INFO: BatchAnalysis begin process traceset
** INFO: BatchAnalysis initialize context
/usr/local/bin/lttv: line 15:  5067 Segmentation fault      $0.real $*


Any ideas?

Best,

-Rilson
