 Oracle EBS Suite Upgrade from 12.1.3 to 12.2.4 - Critical Login Issue 

We have recently upgraded from 12.1.3 to 12.2.4 and after go-live we started seing issues where users randomly getting the error JBO-30012, this was majorly caused by the bug fixes in the initial release and further stabilization and patching in this version fixed the issues, we have upgrade 12.2.6 and later we never seen this issue.

Error:

Error while invoking Main Menu. JBO-30012: A cookie for session g5FHanr4vzZEfS3kbZs5fXxERN and application oracle.apps.fnd.framework.navigate.server.OANavigatePortletAM has already been registered with application pool oracle.prod.orgPAYoracle.apps.fnd.framework.navigate.server.OANavigatePortletAM. The cookie must be removed first.
