Unable to upload attachments in Siebel Application on OCI. The issue has been reported for Siebel product, but it could affect many other products as well.
For Siebel CRM the issue can be reproduced at will with the following steps:
1. Open Chrome or Firefox browser and login in Siebel Application;
2. Navigate to Service Request Details applet and click on Attachment tab, this will send the user to "Service Request detail view w/attachments";
3. Click on Attachment list applet button New File;
4. Select a file with couple of MB on size and click OK;
5. After that the pop up message show up an attachment, but is not uploaded to Siebel.
The issue can be confirmed with fiddler trace output and UI.log from AI Tomcat backend.
In UI.log below events coincide with upload request:

ACTUAL PERFORMANCE
--------------
NOTE: This request was retried after a Send operation failed.
The issue is reproduced only when using OCI Load Balancer (for example, LBaaS Shape: 400 Mbit/s) in front of AI Tomcat. If the LBaaS is bypassed, then the issue is not observed.
Changes
