Last Report on running Job in Unix Agent provoke Forced memory trace dump

Issue/Introduction

After upgrading the AE/AWI to version v21, while keeping some Agents on version 12.x, some Reports are not always displayed during runtime while clicking on "Last Report", this occurs when the size of the report is too large, and generates some force traces at the Automation Engine end, but eventually the Report is displayed correctly.

Snippet of the kind of errors displayed in AWI - Messages:

U00029007 Not all blocks  (Limit 'xxx0) have been transferred from file '/path/to/file'
U00015006 System forced memory trace dump.
...
U00003422 WARNING: Cannot load conversation memory '15cada28' for server routine 'UCDS_R'.
U00011801 Error in server routine 'UCDS_R', Server: 'AUTOMIC#WP005' AE system: 'AUTOMIC'.
...

This can be replicated easily with a JOBS with this code:

x=0
until [ $x -gt 1000000 ]; do
x=$((x+1))
echo "x equals $x"
done

The script will generate the errors when launched on a Unix Agent 12.3.5HF3 and then clicking on "Last Report".

The same will not generate any errors when launched on a Unix Agent 12.3.9 and then clicking on "Last Report".

The same will not generate any errors when launched on a Unix Agent 21.0.5 HF1 and then clicking on "Last Report".
