Backgroundrb devel - Feb 2009 - Problem with scheduled tasks (backgroundrb.yml)

Hi everyone,

I got into trouble with backgroundrb scheduled tasks. I''ve got 3  
workers with number of methods. Somes are running, but others aren''t.  
Here''s my backgroundrb.yml file :

:backgroundrb:
   :port: 11006
   :ip: localhost
   :environment: production
   :user: www-data
   :group: www-data
   :result_storage: memcache
:memcache: "0.0.0.0:11211"
:schedules:
   :maintenance_worker:
     :info:
       :trigger_args: 0 0 10 * * * *
     :check_vd_hourly:
       :trigger_args: 0 0 * * * * *
     :check_vm_hourly:
       :trigger_args: 0 0 * * * * *
     :check_vd_daily:
       :trigger_args: 0 0 3 * * * *
     :check_vm_daily:
       :trigger_args: 0 0 3 * * * *
     :pooler:
       :trigger_args: 0 0 5 * * * *
     :update_count:
       :trigger_args: 0 * * * * * *
     :database_cleaning:
       :trigger_args: 0 25 10 * * * *
   :urls_worker:
     :check:
       :trigger_args: 0 */3 * * * * *
   :wc_worker:
     :check:
       :trigger_args: 0 */6 * * * * *

I wonder if there was any limit to number of processes scheduled?

urls_worker and wc_worker are running correctly, but everything in  
maintenance_worker seems to fail to load without any output in my logs.
