Hi Denis
I am also testing the Fraud Detection module in v2.1.2. I posted some
questions last week, but not had any responses yet.
I have not had any problems with crashing after reload.
My tests have produced code -2 when the critical threshold is reached. My
code snippet is like this:
if (!check_fraud("$avp(userid)", "$rU", "1")) {
switch ($retcode) {
case -1:
xlog("L_WARN", " Route[4]: FRAUD WARNING for call to $rU by
User ID $avp(userid) Call-ID=$ci\n");
break;
case -2:
xlog("L_WARN", " Route[4]: FRAUD ALERT Blocking call to $rU
by User ID $avp(userid) Call-ID=$ci\n");
sl_send_reply("403","Fraud Detect Blocked");
exit;
}
}
I have found that some tests work (like call per minute) whereas others do
not (like sequential calls).
Hope this helps.

Hello!
I am testing Fraud_detection on Opensips 2.1
1) I noticed an Opensips crash after fifo fraud_relaod. GDB from core in
attachment.
2) In the log file i can see such messages "CRITICAL:core:sig_alarm_abort:
BUG - shutdown timeout triggered, dying..."
3) Fraud detection doesn`t work because it shows "code 1" of check_fraud
function during every call, although the function exports event
"E_FRD_CRITICAL".

I made more than 5 calls but there is no "code -2" detected.
Thank you for any help.
