Max Payload exceptions occur when using MessageBroker with chunking

Affected versions

From DataMiner 10.3.0 [CU5]/10.3.8 onwards.

Cause

Fix

Install DataMiner 10.4.0/10.4.1.

Description

When using DataMinerMessageBroker with chunking, it is possible to encounter Max Payload exceptions, which indicate that the packets DataMiner is trying to send are too large.
