Http 400 Bad Request - "Size of a Request Header Field Exceeds Server Limit" (Doc ID 2656231.1)

Last updated on JANUARY 11, 2021

Applies to:

Oracle WebLogic Server - Version 12.2.1.3.0 and later
Information in this document applies to any platform.

Symptoms

 

A consumer application deployed on Weblogic 12.2.1.3 invokes an OSB Rest service. This request is processed by a vanilla Apache with the weblogic plugin 12.2.1.3.0 (not OHS) that redirects the request to one of the OSB server running in the cluster. When the issue occurs the requests aren’t redirected to the OSB servers, an HTTP error code 400 appears in the access.log of the Apache server.

 In this case, the issue occurred only in production environment, restart of the Weblogic server instance is required to fix the issue.
