[OpenSIPS-Users] CGRateS redundancy

[Jens Erik Rive]

Hi, I am running Opensips v.2.4.3 and two instances of cgrates bulidt 10. December 2018.
I am trying to implement redundancy by defining the 2 CGRates servers as:
  
modparam("cgrates", "cgrates_engine", "10.40.2.21:2012") # CGRateS01
modparam("cgrates", "cgrates_engine", "10.40.2.23:2012") # CGRateS02

When I kill (poweroff) the 10.40.2.21 instance and try to call cgrates  with: 
cgrates_auth("$cgr(Account)", "$acc_extra(callee_id)")
I receive -3 (No suitable CGRateS server found) in the response.

I have tested that I can call 10.40.2.23:2012 if modparam("cgrates", "cgrates_engine", "10.40.2.21:2012") # CGRateS01 is omitted from the opensips.cfg script.

Is there anything I am doing wrong?

Thanks,
Jens Erik
