Slave node initialization delay

[GYKrauss]

Using kinetic-devel branch

I have a bus with the ros_canopen master and 3 slave nodes.

Nodes 111 and 2 are intialized almost instantly, but there is a 2 second delay before node 3 is initialized.
Candump snippets:

(1736259833.984677) can0 000#826F
...
(1736259834.276662) can0 000#8202
...
(1736259836.290927) can0 000#8203

Nodes 2 and 3 share the same .yaml config file:
nodes:
left_wheel:
id: 2
name: left_wheel
...
right_wheel:
id: 3
name: right_wheel
...

Any ideas how to debug this issue?
