Reindex process may stuck on ghost vertices, see https://github.com/JanusGraph/janusgraph/issues/1750

Try to remove ghost vertices by GhostVertexRemover

JanusGraphManagement.IndexJobFuture ghostRemover =
    graph.getBackend().buildEdgeScanJob()
         .setJob(new GhostVertexRemover(graph))
         .execute();
try {
    logger.info("GhostVertexRemover statistics: {},{},{}",
        ghostRemover.get().getCustom(REMOVED_VERTEX_COUNT),
        ghostRemover.get().getCustom(REMOVED_RELATION_COUNT),
        ghostRemover.get().getCustom(SKIPPED_GHOST_LIMIT_COUNT));
} catch (InterruptedException | ExecutionException e) {
    throw new RuntimeException(e);
}
