Memory Leak on TcpInitiator openConnection for TCP Extend Clients (Doc ID 2723764.1)

Last updated on JANUARY 16, 2023

Applies to:

Oracle Coherence - Version 12.2.1.4.5 and later
Information in this document applies to any platform.

Symptoms

A significant memory leak has been identified on TcpInitiator for TCP Extend clients that has the potential to cause complete loss of service.

The leak in question exists in com.tangosol.coherence.component.util.daemon.queueProcessor.service.peer.initiator.TcpInitiator#openConnection

On every cache request while the target proxy is down, the openConnection logic in TcpInitiator will add socket handles to __m_CloseOnExit set and doesn't remove them when the attempt to connect/open the socket fails. Over time, __m_CloseOnExit accumulates socket objects until it exhausts JVM heap.
