That likely means that something else was wrong and caused the process to terminate. I have seen that message many times when nodes die (whether because I killed them or something else caused them to crash). A technical explanation of the kind of situation that leads to that error and how to avoid it is given in this answer. That being said, it sounds like your situation is similar to this one, so debugging it may not be straightforward.
Personally, I interpret the message as saying 'the node died', so as long as the node only dies when I kill it, I don't worry about it. If I didn't kill it, then I look for what really caused the node to die.
