[OpenSIPS-Users] load_balance debugging

[Alexandr A. Alexandrov]

Hi!

I have a strange problem with trying to use avps in load_balance function.

I'm trying to do balancing like this:

         avp_db_query("select phone, resource from phone_resource where 
phone like '%$fU%'", "$avp(i:111);$avp(i:112)");
         avp_print();
         xlog("L_INFO","$fu = $avp(i:111)");
         if ($fu=~$avp(i:111)) {
                 xlog("L_INFO", "AAA detected!\n");
                 load_balance("1", "$avp(i:112)");

Here is what I get in logs:

Oct 22 16:35:44 kzo2 /usr/local/sbin/opensips[8214]: 
INFO:avpops:ops_print_avp: #011#011#011id=<112>

Oct 22 16:35:44 kzo2 /usr/local/sbin/opensips[8214]: 
DBG:core:comp_scriptvar: int 26 : -1 / 0

If I write the resource directly, like
                 load_balance("1", "aaa");
everything works fine.
In the above log you can see that $avp(i:112) contains exactly the same 
resource string.
What is the correct way to do this, or is there a way to debug how load 
balancer searches for resources defined in database?

Thanks in advance,
