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

Hi Liviu,

I've applied the patch to both of my machines and it's been running for 
about a week. Everything seems stable and the problem didn't re-appear, 
so I think it's fixed.

Thanks a lot,

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,

Hello,

I've recently migrated my system to 2-node usrloc full-sharing 
cluster. Now occasionally I receive the following error on the 
receiving side:

CRITICAL:usrloc:receive_ucontact_insert:

            differring rlabels (0 vs. 1, ci:

            It seems you have hit a programming bug.

Numbers in the error can be different (8 vs. 9,268 vs. 270).

Config is standard:
