rtpengine recording forwarding only sends one stream on failover

[Poi Poy]

when using tls forwarding with rtpengine-recording and rtpengine with redis. when recording first starts, two tls streams are forwarded as expected. If a failover is forced, both rtp streams are sent to the backup server but only one tls stream is forwarded.

If it is reverted back to the primary server both rtp streams are sent to the primary server and the two streams are forwarded as before

I have confirmed that both rtp streams so switch over, and it doesnt matter which server starts off as the master the behaviour is the same

Should forwarding work in a failover situation?

I think this is an issue with what is stored in redis, as restarting the rtpengine-daemon causes the same issue
