ALSB 2.6 is Causing CLOSE-WAIT sockets by not Closing the Inbound Connections When the HTTP Proxy Client Request Fails With 401 Errors (Doc ID 954522.1)

Last updated on APRIL 14, 2021

Applies to:

Oracle Service Bus - Version 2.5 to 2.6.1RP [Release Aqualogic Service Bus]
Information in this document applies to any platform.

Goal

Each time a client calls a proxy service with HTTP(S) transport, netstat -a shows one more socket in CLOSE_WAIT. After a while, you get thousands of CLOSE_WAIT sockets making the server unavaillable.

This happens if the client fails to authenticate and receives a HTTP 401 error.

In the log file you will find TooManyOpenFileError messages.The number of allowed file descriptors will be used by the java process running the ALSB/WebLogic Server.
