com.google.protobuf.InvalidProtocolBufferException: Protocol message was too large

Hello.

Recently we encountered a stracktrace from a flume agent that is consuming
messages from a RabbitMQ via a File Channel to an HDFS-sink. The stacktrace
is below.
I am wondering if there is a way to configure the
CodedInputStream.setSizeLimit from flume configuration or if there is any
other way around this (making the messages smaller being the obvious answer
of course).
