What happens if you add this to your ansible.cfg?

[ssh\_connection]  
control\_path = %(directory)s/%%C

Maybe your control\_path gets to long (being set to  
ansible-ssh-%h-%p-%r) and thus you run into the BROKEN PIPE error.

Just a guess.

Can you use adhoc commands?

ansible -m ping foobar (for the host foobar)
