I have reproduce you issue.

Seem that is java heap issue.

If the test is producing in one physical machine the issue does not
reproduce, because costs of network communications are small. But when you
are dedicate nodes by others computers, overheads are growing and heap space
becomes insufficient. In result long GC pause or OOM exception and breakdown
topology.

If you wan to avoid this issue you should add enough memory for jvm and
additional tuning you application. Look in his article[1].
