How to Diagnose a Linux Entropy Issue on WebLogic Server Instances

(Doc ID 1574979.1)

Last updated on JUNE 13, 2017

Applies to:

Oracle WebLogic Server - Version 8.1 and later
Linux x86
Linux x86-64

Symptoms

It is observed on some Linux boxes that WebLogic server startup takes several minutes and hangs for a while. Similar behavior happens during the domain creation, when the security information gets populated.

If you take a thread dump on the troubled process you will observe that WebLogic is waiting for random data generation since the OS is running out of entropy.
