problem while deploying with capistrano-unicorn

Hi,

since today I have some issue when I try to stop / start / restart unicorn

I can’t understand why but it seems to be mixing my local user and my server user

on config/unicorn/production.rb I have

user ‘userserver’, ‘userserver’

where ‘userserver’ is the name of the user on server

so when I launch command cap unicorn:restart

I have error u can see here https://gist.github.com/optimum-dulopin/7109877

If I simply change

user ‘userserver’, ‘userserver’

by

user ‘userlocal’, ‘userlocal’

where ‘userlocal’ is the name of the user my personnal computer, then it is working !

do I do something wrong ? I thought that the user in this file should be the on server, not on local machine.

moreover it was working fine the 6 last month !

thanks
