I tried updating to the new multi-line parsing. However this introduced more errors as fluentd had problem parsing some logs. As some containerd logs are diffrent. Because of this i tried adding the cri-parser plugin, but that did not help. Hoverer the errors became more clear. So is not worth updating this at the moment.
