Hmm. Needless to say, that's not what I'm seeing here. I'm on Ubuntu 
10.04 - you?

2.6.1 did something like 'setsid sh -c "/usr/sbin/rabbitmq-server"'
2.7.0 does 'setsid /usr/sbin/rabbitmq-server'

(in both cases with come redirection and environment munging.)

This doesn't feel like something that could cause this failure though.

I'll patch rabbit_management_agent to fall back to lsof if it can't open 
/proc/<pid>/fd, but I'd like to find out why you're seeing this - I've 
googled a bit but can't see anything that would indicate why permissions 
are as they are.

Cheers, Simon
