In recent days, some of our users have encountered an error code where the vtune symbol file was not found. This problem can arise for several reasons. Let’s discuss this below.
Cause and Solution
VTune
Profiler
will warn you that there is literally a module [vdso]
that cannot be symbolically exploded (brackets are used for this), and in addition, therefore, the stack calls may still be faulty. In some cases, it may well be Segment
[vsyscall]
.
You can check if I can say that The
vdso
module works with a dynamic list of dependencies:
