[j-nsp] SRX5k problem

[R S]

We are having a geographic SRX5800 chassis cluster with two redundancy-groups (RG0 and RG1).

We are having many issues while performing the failover of the RG1, with and without preemption. The issue is that when the RG1 becomes active on the node1, real traffic is being lost. Also with preemption, when the node0 becomes again the active for the RG1, lot of traffic is lost.

There are dual Ctrl and Fabric link both through a Layer2 infrastructure, one couple through MX960 and one couple through EX8200.

 Any similar nightmare ?
