Revision history [back]

I found the answer to this question.

It was a communication problem between the openni2_camera node and the roscore node that is on a different machine

My bbb changed it's IP address because of a DHCP lease expiration

After updating the address in the hosts file this error is not occuring again.

Thanks ahendrix for helping me and I hope this thread will help others
