Question:
FIWARE orion: command messages to devices are dropped

Description:
I am running an orion docker container for quite some time
"orion":

together with (not limited to) mongo 4.2.2,, iota-json 1.19.0 and some mosquitto broker (based on 2.11).
I have connected some devices to the platform and measurement data and commands were working well for me.
I believe it was two days ago when the update of attributes in form of sending commands was not working properly anymore and the following error occured:
ERROR@2022-01-27T20:19:13.415Z postUpdateContext.cpp[682]: Orion Bug (empty contextAttributeVector for ContextElementResponse 1)
40% of the commands still arrive at the devices but lots are just lost.
A colleague of mine mentioned we are apparently facing this issue since we updated our VM's OS to Ubuntu 20.04.3 LTS. Still... all components run in docker containers in a swarm (all VMs have the same OS and docker engine version). I also checked the orion container's resources and it seems to be fine, it has pretty low load in fact.
Does anyone have any idea? Thanks in advance
