Memory Leak on the Store-And-Forward (SAF) Service Due to Reconnects (Doc ID 2250609.1)

Last updated on APRIL 06, 2017

Applies to:

Oracle WebLogic Server - Version 10.3.6 to 12.1.3.0.0
Information in this document applies to any platform.

Symptoms

Where a Store-and-Forward (SAF) service has been configured to receive messages, memory usage goes up until WebLogic Server (WLS) crashes due to an OutOfMemoryError (OOME). Heap dump analysis shows that most of the objects are related to unclosed JMS sessions. For example, in a 6.1GB heap, the following values are observed:

Because of this issue, the WLS instance must be restarted frequently (every 4 hours at the most in this example) to avoid JVM crashes due to an OOME.
