Zabbix Sender - Message from x.x.x.x is longer than expected xxx bytes.

[SnIpY]

I'm using Zabbix 3.0 on Docker.

For a particular usecase I need to send data to zabbix. I am using this PHP library.

It works perfectly for my Zabbix 2.4. But I get the following error sending data to Zabbix 3.0. Note: this error appears on the zabbix serverlogs itself.

371:20170105:152004.579 Message from x.x.x.x is longer than expected xxx bytes. Message ignored.

Any idea what I'm missing here? What has been changed causing this to be broken?

just a guess... but it sounds like you might have the wrong "type of information" or the wrong datatype on your item.
