Description

In case influxdb is used as a backend and anything (even completely unrelated things to protocol buffer messages, e.g. manually constructed strings) is written to the data base, then memory grows immediately with protocol buffer internal things accumulating inside the memory:

Actually not a bug, but a feature. RSB event dispatching also queues events and we were faster than influxdb.
