Summary of Problem
What behavior did you observe when encountering this issue?
When I use set to keep the frontier vertices in breadth first search (BFS) algorithm, for a special line graph, the program with 2 locales will break down. However, When I use Domain or DistBag to keep the vertices, no errors happen.
The delaunay benchmark will cause the same error too.

Steps to Reproduce
Source Code:
The BFS codes can be accessed here
// Please provide source code that will reproduce the problem.
// You can insert your code inline if it's not too long.
// Otherwise, you can attach it as a file or provide a URL to it.
// To the extent possible, providing simplified programs demonstrating the
// problem will be appreciated.
// You can also replace this section with "Associated Future Test(s)" below.
Execution command:
The server side will start an arkouda like this
./arkouda_server -nl 2
the client side is like this
python bfs.py nodexx 5555
If an input file is required, include it as well. -->
The line graph is just like this
0 1
1 2
2 3
3 4
4 5
5 6
