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. ``` --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/265

Hi, Can you try with https://github.com/kamailio/kamailio/commit/edc25d7373f9560d09a35640ab19741…, and confirm whether you still observe the same behaviour? Also make sure max_contacts is set the same on all nodes. Cheers, Charles --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/265#issuecomment-129016302

Hi, Is there any chance that edc25d7 will be backported to the 4.3 branch? It would be nice to have it in the upcoming 4.3.2 release. thanks, Paul On 9 August 2015 at 03:33, Charles Chance <notifications(a)github.com> wrote:

Hi, I'm happy to backport, but it depends whether others see this as a new feature or a bug fix. Personally I believe it is essential for the originally intended behaviour, but maybe someone else can comment?

Hi, Do you want to keep this issue open for the save flag 0x04 replace action in dmq_usrloc or do you want to close this one and open a new one for the replace action. FYI, for anyone else looking at this bug report, the particular issue I was experiencing was resolved by either not specifying a flag to save() or using the 0x01 flag and ensuring max_contacts was set properly. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/265#issuecomment-130093889

I'm happy to leave it open since the issue is still there if overwriting contacts (that is, passing 0x04 flag to registrar save function). On 11 August 2015 at 23:16, 00Asgaroth00 <notifications(a)github.com> wrote:

Just looking into this now but I am struggling to reproduce the issue - can you confirm you are still seeing it with the 0x04 flag on save() and that all instances are running the most up-to-date version (with delete replication)? --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/265#issuecomment-134342738

I will re-enable the 0x04 flag shortly and get back to you with findings. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/265#issuecomment-134539846

Hi, I have re-enabled the 0x04 flag now for a while, and I don't see the original behaviour anymore, 0x04 seems to be replacing the contact properly now. I will leave it running like this for a while and see if I see it crop up again. --- Reply to this email directly or view it on GitHub: https://github.com/kamailio/kamailio/issues/265#issuecomment-134563205
