Jobs remains status of Transferring

Products

Issue/Introduction

We have numerous jobs remaining in status Transferring in AWI. Jobs get executed but cannot create their report and remain as Transferring.

In the Agent log, we find the following messages:

U00029002 Report '<RunID>' ended abnormally.

This occurs when there is a high workload on the Agent. So far this has been observed in SQL Agents and Unix Agents

The JCP shows the following messages: 

U00045146 The network module will be re-initialized. All connections will be closed in one second.

Environment

JCPs running on Java 1.8

Cause

This is caused by bugs in Java 1.8 that are unresolved:

https://bugs.openjdk.org/browse/JDK-8011538

https://bugs.openjdk.org/browse/JDK-8238279

These Java bugs are relevant for socket communication. In some instances, the TCP connection does not work properly, and TCP messages through the socket are not delivered, or are delivered with a delay. High workload amplifies this effect of delayed/lost messages.

Resolution

Upgrade the Java used by the JCP processes to at least Java v11.
