Apply DCS 18.104.22.1689+ agent hotfix provided by Broadcom on AIX hosts or upgrade to the DCS 6.9.0 Agent.
This hotfix fixes the crash by improving the spinlock initialization. Additionally this hotfix gives functionality to disable VNode caching at runtime. By default it is enabled on system boot up.
