OSB Managed Server randomly stops responding to requests after upgrading to 12.2.1.3 from 12.2.1.2 when using UseEnhancedIncrementAdvisor (Doc ID 2442093.1)

Last updated on APRIL 17, 2023

Applies to:

Oracle Service Bus - Version 12.2.1.3.0 and later
Information in this document applies to any platform.

Symptoms

Seeing problems with OSB managed servers in PROD, where the server will not response to any requests for a few seconds. There are no stuck threads or hogging threads, but the current open sockets rise from a normal value of 100 to 1000.

Switching the socket muxer from NIO to POSIX doesn't not help

Also could see issues in OTD if using an OTD to balance the request (in front of the OSB servers).

Changes

 Issue started to occur after upgrading OSB from 12.2.1.0 to 12.2.1.3
