JanZerebecki added a comment. This happens only on zend. This error can not be found in logstash as it seems that warnings from zend do not get sent there. So I assume this means it happened on terbium.
From my reading this would happen if we get from the DB a value that is either null or the string "N;" ( = serialize(null); ) or the string "null" ( = json_decode(null); ) or some invalid json or json deeper than the recursion limit (the two cases where the docs say json_decode returns null). From running a few queries there seems to be none of the first 3 cases in the DB. No easy way to test the later two with just a mysql console. Maybe a failed DB connection?
