Tomcat server running AWI hangs

Products

• CA Automic Workload Automation - Automation Engine

Issue/Introduction

We have migrated AWI to Redhat, this resulted in a freeze of Tomcat about once a week. No login was possible.
After restarting the Tomcat server the problem was resolved.

We checked that Tomcat still had enough free memory and the CPU utilization was practically 0.

Cause

The backend was sending Messages to AWI whenever they were generated, this resulted in Tomcat being overloaded.

Environment

Release : 12.3

Component : AWI

So far the issue has only been observed with Tomcat on Linux.

Resolution

The issue has been resolved in AWI v12.3.8 (Available).

Now Messages are only sent to AWI in batches each second.
