+## Use monolog from your kernel

 ## Running a worker without forking
 
-Sometimes intensive tasks may lose performance with forking mode. We have added a bin/resque-single binary, you can pass kernel file to be loaded only once at start. Be carefull cause if this Worker fails, then you need to restart manually this worker. We recommend to use supervisor to control this, and superlance with memory plugin to restart worker when hits some memory treshold.
