I don't think this is new for this build - might have been true for 6 months or so, but the --wipe option to scanner has a bug that causes the scan to stall after the second stage (Scanning new music).

The last thing in the log is
[18-02-20 22:47:34.6499] Slim::Utils::Scanner::Local::__ANON__ (454) Rescanning changed audio files (0)

Process must be terminated with kill -9 (normal kill/abort is insufficient).
