Split brain happen on SRX1500 due to Fabric monitor down?
This is third time i'm facing issue split brain issue on SRX1500 cluster due to Fabric monitoring down. Previous case JTAC said hit PR but now it happen again. The fabric and control link connected direct withouth through any interconnect device. I'm really disappointed because it already third time happen even previous already escalate to Engineering level. But it still happen last night. So my question what the possiblity that can make "Fabric Monitoring" down as below output:

Control interfaces: Index Interface Monitored-Status Internal-SA Security 0 em0 Up Disabled Disabled
Fabric link status: Down
