[SR-Users] Kamailio stops processing requests mid script

Hi Daniel,
I've followed your suggestions and compared this "bad" server with the two
"good" ones.
- Pike:
In all cases we have:
if (src_ip!=myself && !ds_is_from_list()) {
if($sht(ipban=>$si)!=$null) {
xlog("L_ALERT","ALERT: blocked by pike R=$ru from $fu
(IP:$si:$sp)\n");
exit;
}
if (!pike_check_req()) {
xlog("L_ALERT","ALERT: pike blocking R=$ru from $fu
(IP:$si:$sp)\n");
$sht(ipban=>$si) = 1;
exit;
}
}
And we are not seeing any logs, therefore I'm discarding pike.
- Firewall:
I checked all 3 servers, and none of them have -local- firewall policies.
- conntrack:
All 3 servers have nf_conntrack loaded in kernel.
- selinux/etc:
The two good servers have "AppArmor" disabled.
The bad server has "AppArmor" enabled. !!!!!!!!!!!!!! <---------- I'm
hoping this could be the cause and I'm going to test tonight without it.
Thanks for checking this, I was so lost I actually went ahead and did
"kamctl trap" last night too just in case. When I run it, it didn't stop by
itself (I stopped it with CTRL+C after some time) but it did generate a
file with a lot of output. Can I send you it privately? I'm not sure how to
interpret it.
Before anything I'm going to test tonight:
1- disabling apparmor
2- unloading nf_conntrack
I'll report back with the resutls.
