Hi Anand, 

This bug report lacks a lot of information we need to reproduce the 
issue. We'll soon come up with a "bug report guideline" on the lttng.org 
website. 

Also, we can't help but noticing that the amount of support you have been 
requiring those past months seems better suited to the commercial LTTng 
support offered by EfficiOS. In addition to give you the amount of support 
you need, this is one of the main mechanisms for funding LTTng project 
maintenance work. 

Best Regards, 

Mathieu
