Integer overflow in TCP comm

See original GitHub issue

What happened:

I am receiving integer overflow errors in some large scale computations. Haven’t had the chance to construct a MCVE but will try to.

cc @jakirkham I believe you reworked this section recently. Maybe you spot what’s going wrong right away

What you expected to happen:
