[OpenSIPS-Users] Not enough memory to sync cluster data

[Răzvan Crainea]

@Alexei: unfortunately there is no way in OpenSIPS to auto-scale the 
private or public memory - you'll have to decide from the beginning how 
much traffic you are going to support and scale the memory usage 
accordingly. Syncing cannot be done using shared memory, so the only 
solution I can see is to increase the pkg (-M) parameter to a 
comfortable value.

@Mohit: In order to use cluster replication for dialogs, you can follow 
this[1] tutorial, or this[2] one for usrloc replication.
Both methods require a full working cluster. For details about cluster 
configuration, please read the module's manual[3].
