This is a snip from the user's mailing list, I'm just adding it to the issue tracker, as it is yet to be confirmed as a bug, only here for tracking pruporses:

I have a situation where I have 2 devices registering with the same AOR, I have the registrar module's max_contacts parameter set to 1 and I use the 0x04 flag on the save function.

When I use dmq_usrloc for replication, I can see 2 contacts registered for the AOR on the "client" nodes whereas the node where the actual registration took place only has 1 contact for the AOR. 

It seems to me like another bug, although again I'm not familiar with the module so can't be sure without looking that it is not intended behaviour.

I plan to look later this week when I have some time but in the meantime, you can send me the examples directly if you like.
