Pool limits

Yes: CentOS 6.5 and Fabric 1.10.0. I need to run some light commands on ~ 1000-2000 fabric servers. My env in fabfile.py:

env.parallel = True
env.pool_size = 500

      

        
        
        
      

    

So when I start using fab and view the processes:

# ps ax | grep fab|wc -l
106
# ps ax | grep fab|wc -l
121
# ps ax | grep fab|wc -l
106
# ps ax | grep fab|wc -l
108

      

        
        
        
      

    

Why don't I have a real pool size of 500 processes, ~ 100 in total? Could there be OS limitations?
