Takes too long to restart the Weblogic Managed Servers

If your Weblogic server startup takes too long, then you might be running into entropy bug that can be fixed in one of the 3 ways:

1. Patch /jre/lib/security/java.security by replacing the line "securerandom.source=file:/dev/urandom" with "securerandom.source=file:/dev/./urandom"
2. Add JVM argument -Djava.security.egd=file:/dev/./urandom to the startup scripts
3. Create a symlink for /dev/urandom to point to /dev/./urandom
