Hi,

I've not seen this behavior before with 2.4, so it's definitely 
strange.  You can force a sync of ALL dialogs at any time via the 
"dlg_cluster_sync" MI command [1]. The same logic gets invoked on the 
backup during startup, so let's see if you run into the same "partial 
sync" issue you're experiencing.  Make sure to grab the final 2.4 
version before proceeding, though -- the issue might just go away by 
pulling the latest fixes.

Once you eventually decide to upgrade to a supported version such as 
3.2, you will gain access to even better dialog clustering, where the 
backup node is able to self-recover its data by automatically issuing a 
sync request afterany temporary network disconnect, thanks to the 
"cluster_auto_sync" setting [2].
