We have a SRX1400 cluster running on JUNOS Software Release [12.3X48-D35.7]. I was running some Failover test cases. In one of the cases, when we power off primary node, the failover works fine but, after powering on the primary node, few minutes later (6 minutes to be precise), the traffic stops between the zones for almost 10 minutes and then cluster comes back to normal operation.
I also tried removing the "preempt" parameter but, results were same. Please let me know how to eliminate this downtime.
