doesnt work the collection of statistics generated

I tried to use recommender api with "Browsing History Recommender" but doesnt work the recollection of statistics generated in the environment of drupal (visit of nodes, etc).

Environment:
-------------------
Drupal 7
Linux mint 11
mssql5
modules:
instalation: standalone (Apache Mahout and drupal server in the same server)
recommender api, 7.x-4.0-alpha14
Async Command, 7.x-2.0-alpha10
statistic, 7.12
Browsing History Recommender, 7.x-1.0-alpha6

Problem:
------------
When I run the "run.sh" script the result is:
