[Fab-user] sudo fails every now and again

[address@hidden]

Hi

We manage our DNS changes through GIT, moment a change happens, a post-receive script of git checks the dns zones files

into a nfs mount on the DNS server, it then executes a fabfile that pretty much only does a sudo("service bind9 restart"), everything works

great.....most of the time. About 2 in 10 times, the fabric script fails with this error.

I do the authentication through a keyfile as follow :

env.user = 'afit'

env.key_filename = '/opt/git/.ssh/id_rsa'

Anyone have any idea?
