Collect locks and waits data failed

Hi,

I run vtune on linux (redhat 7.1) ,use the gui tool. when I collected the locks and waits type, collection can not continue:

Application sets its own handler for signal 38 that is used for internal needs of the tool.

but other type of analysis works well.

what's the problem and how to fixed it ? I want to collect locks and waits data of my system.

thank you.
