Hi,

I have pushed a change to master which should prevent the crash.

You'll still need (for now) to use "location" in save/lookup - I will add multi-domain replication later but there needs to be some enhancement to the usrloc API first.

Please confirm this fixes the crash and I will backport to 4.3.

Cheers,
Charles

i think we should support custom location tables in the future but either way,
i tried changing location to kam_location in 2 instances on usrloc_sync.c -- crash
i tried changing save("location") -- crash

Hi,

I'm not sure why, but the dmq_usrloc module was written with the usrloc domain hardcoded as "location".

I intend to address that along with some other improvements but in the meantime, try changing your call to save() to use "location" instead of "kam_location"...

save("location");

Please report back the result.

Cheers,
Charles

Hello,

From which version has this been generated?

Also, can you provide the output of "kamctl ul show" and the relevant modparam sections of your config (usrloc, dmq, dmq_usrloc).

Cheers,

Hi,

 

Yes, I do see it replicating contacts to the other 2 servers on the dmq bus, however, I did come across a strange issue with the max contacts parameter, which the devs are looking at:

have you seen your usrloc actually populate data from another server?

i can verify my dmq is working properly. just usrloc not populating.

Hi,

 

I’m a new user to the dmq subsystem in kamailio, but, once I had a properly configured dmq environment and loaded dmq_usrloc after dmq, all I had to do was add the following to the module paramters:

 

modparam("dmq_usrloc", "enable", 1)

 

Then in the routing logic of the registrar’s you just need to add the appropriate dmq message handling blocks.

 

Hope this helps in some way.

is there any function to trigger replication?

 

i enabled the module and dmq is working for my htables

but usrloc is not replicating.

 

"kamctl ul show" does not show anything

 

i used ngrep to trace the KDMQ packets, i can see the frequent exchanges but nothing related to usrloc. am i doing something wrong?
