Every 10 minutes, RP got a Error.

Hi. We are using RP 5.1 and control 6 consistency group. When we start the data transfer, RP always got a error every 10 minutes with below error Error detail : 1. Pausing data transfer to copy - Description : peer must reestablish connection 2. Pausing data transfer to copy - Description : Handshake communication state bad 3. Negotiation of transfer protocol successful again. We and out network team check the our line but there is no issue about network because some consistency group was completed replication with these error (These group has a little size and disk I/O) We are using two network line, one is MPLS(3.5Mbps), other is satellite(6Mbps) Our network team configurate RP1 to satellite and RP2 to MPLS. In this case, what can we check the system for clear the error?

If multiple Consistency Groups (CGs) are in Long Resync state you need to pause them and resume transfer them one by one.
The customer can use Bandwidth Limitation option on CGs.
The customer will need to check his network to identify bottlenecks.
Engage Pre-Sales team to re-size the customer environment even environment has grown and needs to increase WAN Bandwidth.
If errors are during specific times where a high change rate is happening, if RPAs CPU is not passing 40-50% you can attempt to increase compression.

I would highly recommend looking at packet loss % (make sure it's consistently <1%) as well as uniform MTU end-to-end.
