When an SNMP trap arrives at the event console which can't be parsed for various reasons (unknown SNMP engine ID, some deserialization error, ...), we previously logged a full Python backtrace to the EC log. This could lead to the incorrect conclusion that there is something wrong with the EC itself, which is not what has actually happened: Actually, some device was probably misconfigured and/or misbehaving. To avoid such log spam, such a trap is now silently dropped at the standard "informational" log level, and more details can be logged at higher levels when needed.
