Configure a CLM server under "administration/clm". Then shut down the CLM server. Now go to "administration/capabilities". This will fail with a UI timeout.
This is particularly bad because there is no way to clear out the CLM server settings under "administration/clm", the UI won't let you.
To fix this, you need to temporarily increase your UI timeout to be > 90 seconds, then go to the CLM capability (when it finally loads) and disable it.
