It seems you are trying to create a socket within the source directory, which fails if the source directory is in a deep path because there is an OS limit on the maximum length of a socket path. Perhaps you should create the socket in /tmp or $TMPDIR instead.

Avoid long socket paths in KCM tests

The build directory path may be too long for a Unix domain socket, so
use a path in a temporary directory instead. Reported by Ryan
Schmidt.
