    Dear all,

    still struggling with SRX1500 :) We had issues with version 18.4R3.3 (especially with failover or RG0), so decision was made to go to version recommended by Juniper, which couple of weeks ago was 19.4R3-S1.3 (Junos Software Versions - Suggested Releases to Consider and Evaluate - Juniper Networks). 

    After upgrading to this version we have observed strange behavior of cluster. When node0 is a master for RG1, we are not getting multicast traffic from subsystems, whose traffic is going through reth4 interface (multiple vlans on this, physical interfaces are ge-0/0/4 and ge-7/0/4). But when node1 is master for RG1, everything is OK.

    Any ideas what can cause this issue?

    Best regards
