The KB article actually mentions flooding the vmware.log file on the datastore too:
In the vmware.log file for the virtual machine, you see log spew of this error:
GuestRpc: Channel X reinitialized.
Though I have to agree that it seems a bit extreme if this ends up filling your datastores.
Hint: Use the log.keepOld and log.rotateSize VMX-parameters to limit the logging volume to some sensible degree (mentioned in the vSphere Hardening Guide too).
