My next question would be whether this particular process shown is
stack is stuck forever or finally, it is able to make a connection?  I
want to understand is this just due to slow I/O or something else?

They don't ever seem to clear, (more and more show up)  and IO doesn't seem to be deadlocked at that time.

It's a really odd one!
