In all likelihood, yes, that's exactly what caused it. The files are
normally removed when Jack terminates cleanly, and the files are the
only method Jack has to determine if another copy of Jack is running.

Rebooting is not necessary. Rebooting will not clean up the files.
After some bad system event, like pulling the power, you just have to
do it by hand.
