“Linux on the server is known for not crashing, but it
can and does crash and hang. What’s the difference between a crash
or a hang at the application level, as opposed to the
kernel?“Mark Wilding: A crash or a hang at the
application level is isolated only to a particular thread or
process. The crash or hang will not directly cause other unrelated
processes or threads running on the same system to crash or hang.
At the kernel level, a crash or hang will affect all processes
running on the system…”
