Description

Shameless pasting from an email conversation with Jonathan <>:

On your other email chain, you have discovered a bug in the communication-aware load balancing code, where the graph assumes that every edge will always have both nodes. This is obviously not true in the case of deletions and insertions (or even just periodic load balancing when the state may not be clearly defined)

Could we get the full context of that conversation, to allow others in the group to track this down? Or, if there's a test case that exercises it, we can work through it that way.

I'll try to see that this gets looked into shortly.
