I have been facing a strange behavior of zabbix trapper component. I have been tryind to send a list of SQL Server jobs as a discovery message. I have sent the same message twice.

First one was successfully processed.
Second one failed with response "cannot parse as a valid JSON object: unexpected end of string data".

Second message was shortened as you can see in log attached.

Data length of the massage was 2541 bytes. A message with more bytes is not processed at all.
