Error description
A single CDRNs thread does not run efficiently when ER encryption is turned on and multiple crypto VPs are running. The provided reproduction will show the CDRNs thread bounces back and forth from a ready state waiting to run on 1crypto to a running state usually on 4crypto for well over an hour when 4 crypto VPs are defined. During this time, you can usually catch the CDRNs thread in ready with the following stack: yield_processor_mvp mt_yield mt_bind_class CryptoBind CryptoEncrypt nifiSendBuf nifStdSend nifSend nifGenericAccept cdraccept listen_verify spawn_thread startup
Local fix
If you use "onmode -p -1 crypto" to drop crypto VPs such that only one remains before the CDRNs thread starts or while it was running, it will finish its work in less than 2 minutes versus the ~1.5 hours that it will take to encrypt and send otherwise.
