It is easy to reproduce, just call exec_avp with sh script which has sleep 1 min.
Please find below part of configuration file where the exec_avp is used:
failure_route[HANDLE_FAILURE_ON_INCOMING_REQ] {
if (t_is_canceled()) {
exit;
}
if (t_branch_timeout()) {
if (t_branch_replied()) {
// A local timeout after some provsional reply.
xlog("L_WARN", "No final response on request $rm CSeq:$cs
($ci)!\n");
} else {
// A local transaction timed out w/o any reply received.
// In case incoming calls that means out Telephony doesn't reply.
xlog("L_ERR", "Failover on request $rm CSeq:$cs
($ci)!\n");
// Set current Telephony to inactive probbing state
ds_mark_dst("IP");
// Checking next endpoint from the destination list
if (!ds_next_dst()) {
t_reply("503", "Service Unavailable");
xlog("L_CRIT","Failure route: All Telephony servers are
invactive!\n");
if ($shv(is_zabbix_event_sent) == 0) {
$shv(is_zabbix_event_sent) = 1;
exec_avp("etc/kamailio/run_zabbix_sender.sh
ecsp_no_telephony");
xlog("L_NOTICE","ecsp_no_telephony event is sent to
zabbix\n");
}
exit;
}
xlog("L_ERR", "Try to send to $rd:$rp ($ci)\n");
route(RELAY);
}
}
}
