Entries In the Coherence*Web Local Attribute Cache Are Not Reaped After The Session Expires
(Doc ID 1607367.1)
Last updated on SEPTEMBER 20, 2023
Applies to:
Oracle Coherence - Version 3.7.1.9 to 3.7.1.16 [Release AS10g]Information in this document applies to any platform.
Symptoms
Customer is facing a memory leak in WebLogic Server instances, where they are sharing a subset of Session attributes among two different webapps using Coherence*Web. This memory leak eventually fills the entire heap of the WebLogic Server instances, leading them to an unrecoverable state which requires the instances to be shutdown and restarted.
Heap dumps on the failing WLS instances show how the main leak suspect points to a cache used by Coherence*Web to store locally the session attributes (local-attribute-storage). This cache is the one that increases its size until the crash of the WebLogic instance with an OutOfMemoryError
