[Fab-user] Dropped output messages?

[Evan Jones]

I'm just starting to test Fabric using the latest version in GIT. I'm 
running into an issue where some of the output from my tasks does not 
appear on the command line. Am I screwing something up? My test job just 
runs the "uptime" command on a bunch of hosts. The problem seems more 
likely to occur if I have more hosts in the list. With 3 it seems to 
never happen. With 4 it happens on occasion. With 6 it seems to happen 
every time I try it.

Thanks for your help,

Evan Jones



My fabfile.py:


from fabric.api import *

env.hosts = [
        "farm6.csail.mit.edu",
        "farm7.csail.mit.edu",
        "farm8.csail.mit.edu",
        "farm10.csail.mit.edu",
        "farm11.csail.mit.edu",
        "farm12.csail.mit.edu",
]

def  deploy():
    """Deploy the job!"""
    run("uptime")



Sample output with the problem. Notice that the uptime output from 
farm10 is missing:

[farm6.csail.mit.edu] run: uptime
[farm6.csail.mit.edu] out:  10:22:56 up 131 days, 21:57,  0 users,  load 
average: 0.00, 0.00, 0.00
[farm7.csail.mit.edu] run: uptime
[farm7.csail.mit.edu] out:  10:22:56 up 131 days, 21:56,  0 users,  load

[farm10.csail.mit.edu] run: uptime
[farm11.csail.mit.edu] run: uptime

load average: 0.00, 0.00, 0.00
