[SR-Users] usrloc_dmq - Suddenly stopped usrloc replication

[Henning Westerholt]

Hello,

It might be something during the restart, that some of the processes did not started correctly due to still allocated resources from the “old” processes still running. Maybe a race condition in this particular system environment, but hard to say if you cannot reproduce it.

Cheers,

Henning

no, I'm pretty sure that didn't happen, I don't have any other config files there.

Maybe you restarted with a different config file?

Hi Ovidiu,

I compared both logs and when kamailio didn't started all processes, there is missing the log msg from usrloc_dmq:

INFO: dmq_usrloc [dmq_usrloc.c:77]: mod_init(): dmq usrloc replication mode = 1

But I still have doubts why it happened, do you guys know any possible reason that could make this happening?

Thank you

Best regards
José

Compare the logs for the two cases. Also, check if there are any error
logs for the case with missing processes.
