Hello,

it looks like sock_avp parameter has to be set -- it is there before 4.3.0 release, as I could spot in 'git blame' for dispatcher.c:768.

Not sure is really needed for failover, I will check its usage when I get first chance.

Hello!

We noticed today an issue with the kamailio loadbalancing.

Basically kamailio is not considering if an host is up or not, backends are set always as "FLAGS: AP" even if the host is down.

I see this when the proxy starts :

ERROR: dispatcher [dispatcher.c:768]: ds_warn_fixup(): failover functions used, but required AVP parameters are NULL -- feature disabled

These the parameters I have set:

# ----- dispatcher params -----

modparam("dispatcher", "list_file", "/etc/kamailio/dispatcher.list")

modparam("dispatcher", "dst_avp", "$avp(dsdst)")

modparam("dispatcher", "grp_avp", "$avp(dsgrp)")

modparam("dispatcher", "cnt_avp", "$avp(dscnt)")

modparam("dispatcher", "ds_ping_method", "OPTIONS")

modparam("dispatcher", "ds_ping_reply_codes", "class=2;class=3;code=404")

modparam("dispatcher", "ds_ping_from", "sip:proxy@sip.nexmo.com")

modparam("dispatcher", "ds_ping_interval", 20)

modparam("dispatcher", "ds_probing_threshold", 1)

modparam("dispatcher", "ds_probing_mode", 1)

modparam("dispatcher", "ds_hash_size", 10)

modparam("dispatcher", "ds_hash_expire", 3600)

modparam("dispatcher", "ds_hash_initexpire", 60)

modparam("dispatcher", "ds_hash_check_interval", 10)

modparam("dispatcher", "use_default", 0)

modparam("dispatcher", "attrs_pvname", "$avp(carrierattr)")

modparam("dispatcher", "setid_pvname", "$avp(carriergroup)")

modparam("dispatcher", "flags", 2)

I use 4.3.3, I think this issue started after upgrading from 4.3.1 but I can't say for sure.

Can someone please give us some advices on this?

Thanks

Alessio
