IOException handling improved to resolve broken pipe errors
Resolved in Pega Version 8.1.9
Frequent "connection reset by peers" exceptions were being generated and broken-pipe exceptions were seen in the logs. Investigation traced the issue to unhanded IOExceptions on the server side that were a result of the client application not always closing the TCP connection gracefully. To resolve this, error handling for IOExceptions has been improved.

QP exception handling improved
Resolved in Pega Version 8.1.9
There is currently a configurable maximum size limit for QP items of 5MB. If the message size exceeded 5 MB, the message failed to be enqueued to Kafka, but still ended up in the delayed message table where it remained. This caused issues with pzDelayedQueueProcessorSchedule JS as a result. To resolve this, the system has been updated to better detect Kafka errors related with message size and move any corrupted item to the broken message queue with the appropriate message attached.
