Summary: load_balance does not return next gateway
Initial Comment:
Calling load_balance() twice in request route does not return the next gateway in the set.
route[2] {
load_balance("$avp(778)","pstn","1");
xlog("L_DEBUG", "\n===DESTINATION IS $du===\n");
load_balance("$avp(778)","pstn","1");
xlog("L_DEBUG", "\n===DESTINATION IS $du===\n");
if ($retcode<0) {
sl_send_reply("503","Service Unavailable - NO GATEWAYS");
exit;
}
xlog("L_DEBUG","\n===CHECKING RATE LIMIT FOR $du===\n");
if(!rl_check("lb_$du", "0", "TAILDROP")) {
rl_dec_count("lb_$du");
route(2);
exit;
}
xlog("L_DEBUG", "Selected destination is: $du\n");
# send it out
if (!t_relay()) {
sl_reply_error();
}
exit;
}

Hi Matt,
This bug is similar to 3604147 , which I just fixed. The marking of the
used destination (during the failover) was bogus if the destination ID was
higher than 8.
SVN is updated trunk, 1.9, 1.8, 1.7 , so please do not use the patch I
sent, update from SVN and try again, it should work now.
Regards,
Bogdan

Please re-run your test with the attached patch which will provide more
debug info - and post here the logs from lb modules.
Thanks and regards,
