(Doc ID 2670336.1)
Last updated on JUNE 07, 2022
Applies to:Oracle WebLogic Server - Version 18.104.22.168.0 and later
Information in this document applies to any platform.
Noticing the high memory consumption on the object "weblogic.cluster.replication.WroManager", which was not releasing memory after load test.
The environment was having 6 servers in a Cluster. Also using a custom Java Application with the default "in-memory" for HTTP session replication. Noticed that during the load testing, after 2 hours the server OS runs out of memory (OOM). Upon taking a heap dump, noticed that the memory allocation on the heap is due to the object "weblogic.cluster.replication.WroManager" which was consuming most of the memory. The memory did not get released even after the load testing concluded.
That memory was not released until the restart of the managed servers.
