ORBIT-USER: error with imaging nodes

[Max Ott]

As a general rule, please include your experiment ID in all questions
about nodehandler errors. Without that it is very difficult to find
out what really went wrong. In your case, the communication link to
the nodes seem to have died, but the snippet you posted doesn't tell
me more than that.

Please try again and see if it happens again.

Remember, you are controlling a highly distributed system with many
unreliable components. We are trying hard to catch many of the errors
which can occur and try to recover from it, but it is far from perfect
and may never be.

Thanks,
