Hello list.
I’m having some issues with the Kamailio versión 3.2.0.
I want to ask if someone could give some hints how to optimize the
performance of my kamailio server. For some reason and from time to time
the kamailio process start to answer slower than usual, making calls fail
and register expires. I’m still unable to detect the problem, but I want
to know of maybe i´m running my kamailio not under the best conditions.
This is part of my configuration :
#!KAMAILIO
#!define FLT_NATS 5
#!define FLB_NATB 6
#!define FLB_NATSIPPING 7

I’m using pike to check flood alerts, but I have a white list stored in the
“user_preference” table :
I’m using it like this :
route[REQINIT] {
# flood dection from same IP and traffic ban for a while
# be sure you exclude checking trusted peers, such as pstn gateways
# - local host excluded (e.g., loop to self)
if( !(avp_db_load("pike", "$avp(ip_origen)") &&
avp_check("$avp(ip_origen)", "eq/$src_ip/gi")) )

{
if($sht(ipban=>$si)!=$null)
{
# ip is already blocked
xdbg("request from blocked IP - $rm from $fu
(IP:$si:$sp)\n");
exit;
}
if (!pike_check_req())
{
xlog("L_ALERT","ALERT: pike blocking $rm from $fu
(IP:$si:$sp)\n");
xlog("L_INFO","ALERT: pike blocking from
$si\n");
$sht(ipban=>$si) = 1;
exit;
}
}
Is this check method too slow? Or intensive in mysql access request??
Hope someone can help me here.
Thanks in advance..
