Hi all,

When I follow the chef-expander and the chef-expander worker process

with strace, I get the following output:

I don't really understand the output, but I get the impression something

is wrong here. How does it look on a working system?

On very rare occasions I get something like this in the chef-expander

worker strace output:

Is this how it looks when chef-expander does what it should?

Thanks in advance.

Is there a firewall dropping packets to rabbitmq?
