The problem is that this system has a default libc that has been compiled without frame pointers, so any stack walking stops at the libc layer, producing a partial stack that's missing the application frames. This is pretty common and usually goes unnoticed as the flame graph looks ok at first glance.

An assertion documents the expected state of specific program variables at the point where the assertion is written, in a testable way so that we can find program bugs — logic errors that have led to corrupted program state. Assertions are only about finding bugs, not doing program work.

Selenium was first conceptualized in 2004 at ThoughtWorks for website automation and has come a long way from it’s first Web Driver version to becoming a W3C standard protocol.

Created by Alastair Robertson , bpftrace is an open source high-level tracing front-end that lets you analyze systems in custom ways. eBPF (extended Berkeley Packet Filter) is in the Linux kernel and is the new hotness in systems engineering. bcc is powerful but laborious to program. It's shaping up to be a DTrace version 2.0:
