[OpenSIPS-Users] usrloc replication error: differring rlabels (0 vs. 1, ci: 'b7b3f2f3-38f32b64 at 192.168.10.87')

[Liviu Chircu]

Hi Michael,

I've been working on this problem recently and there is a patch 
<https://github.com/OpenSIPS/opensips/commit/90a00795b1d0685394818c4a69c235f487389878> 
which has already received some amount of testing to be deemed stable, 
hence I just decided to push it to master branch.

If you could pull it into your setup (both boxes) and confirm there are 
no side-effects, that would help make the backport to 3.5 and 3.4 a lot 
safer!

Best regards,
