Mark Payne commented on NIFI-3182:
----------------------------------

This appears to have been addressed already in version 1.1.0, as this processor was heavily refactored for NIFI-2865.

> If PublishKafka is configured to send using a delimiter, and it receives a FlowFile whose content contains the delimiter, and that delimiter ends at the 8 KB mark (8192 bytes into the FlowFile Content), then PublishKafka will get stuck in an infinite loop, sending the same message over and over.
> To replicate, create a simple Flow:
> GenerateFlowFile -> ReplaceText -> PublishKafka
> For GenerateFlowFile, generate a message that is 8187 bytes.
> With ReplaceText, configure it to always append the value "HELLO" (without quotes).
> Configure PublishKafka to use a demarcator of "HELLO" (without quotes).
> When PublishKafka attempts to send the data, it will continually send the randomly generated data over and over and over, never relinquishing its thread.
