@pfefferle @laurenshof We also try to catch JSON parsing errors... https://github.com/MbinOrg/mbin/pull/1098 (thank you @BentiGorlich)
Hopefully that solve the issue at our side as well. We just noticed that it was ending-up in some kind of loop. We are still unsure why it was constantly trying to create a message. Look: https://pastebin.com/M4vhsdRh (it could be a loop issue in RabbitMQ, or the server is spamming, constantly sending requests?)
Ps. Is this just a small snippet of the log.
