WebLogic Server's Queue Length Count Increases Over Time and Never Decreases (Doc ID 1509691.1)

Last updated on SEPTEMBER 09, 2018

Applies to:

Oracle WebLogic Server - Version 10.3.6 to 12.1.1.0
Information in this document applies to any platform.

Symptoms

In WebLogic Server we may observe that the queue length (Server --> Monitoring --> Threads) value keeps on increasing, but never comes back until the servers are restarted. This behavior will not cause any performance impact.

The pending user request count is Zero, which means, if the Queue length value displayed is correct, then it should be the pending count for internal RMI requests.

In the heap dump, under weblogic.work.RequestManager, we only see one Queue, i.e., weblogic.work.CalendarQueue.
