Coherence Extend Client Get Request Timeouts When Using Secure SSL Connection to Extend Proxy (Doc ID 1593837.1)

Last updated on NOVEMBER 03, 2016

Applies to:

Oracle Coherence - Version 3.7.1.5 and later
Information in this document applies to any platform.

Symptoms

When using a Coherence 3.7.1.x Extend Client, the client requests receive a RequestTimeOutException when fetching data from a cache, as shown below.  Later, when retrying the same query for the same data/key that failed, the request completes successfully.  The timeout can be encountered with a simple NamedCache.get() that returns a large response, for example over 8Kb. There is no concurrency used by the client and it is set up to connect to the Extend Proxy server using SSL.  The problems appears to be easier to encounter when the client is running on Windows 2008 R2, but it does happen on other operating systems like Linux, just less frequently.

This issue happens regardless of Java JDK version used.
