[Fab-user] parallel execution get stack when run on long list

[Wawrzek Niewodniczanski]

Hi,

I have following problem.

I try to run a fab command on over 300 hosts from MacOSX using lates
fabric from pip. The command is anythting fancy (see below), but it
gets stack. I see some python processes which never end. When I split
the same list into 3 everything works fine with great speed. Any idea
what's wrong? The command has to be fine, connections are fine, I use
pool_size (try different value, effect the same) so I don't use too
much resources.

My fab file currently looks this:
from fabric.api import *

env.skip_bad_hosts =True
env.warn_only = True
env.parallel = True
env.show = ['debug']

@parallel(pool_size=5)
def taskA():
    out = sudo('/sbin/swapoff -a')
    print out.failed
