[OpenSIPS-Users] Help with my OpenSips architecture

Thu Aug 9 05:29:37 EDT 2018

Hi Dominic,

The state listed by 'clusterer_list_cap' refers to the startup 
synchronization mechanism. When you register a sip device on an 
instance, that event is replicated on the spot to the other instances in 
the cluster, but older registrations are only pulled from other nodes at 
startup. You probably did not set the "seed" flag for any of the nodes, 
so the syncing process is unable to bootstrap correctly.
