### Description
We are using Kamailio 5.7.4 on Debian 12 (from http://deb.kamailio.org/kamailio57) with rtpengine as an Edgeproxy for our clients. The instance terminates SIP/TLS (with Cliencertificates) and forwards the SIP Traffic to internal systems.
After some days we are getting errors like this
`tls_complete_init(): tls: ssl bug #1491 workaround: not enough memory for safe operation: shm=7318616 threshold1=8912896`
First we thought Kamailio just doesnt have enough memory, so we doubled it..
But after some days the Logmessage (and Userissues) occured again.
So we monitored the shmmem statistics and found that used and max_used are constantly growing til it reaches the limit.
As i mentioned we are using client-certificates and so we are also using the CRL feature.
We do have a systemd-timer which fetches the CRL every hour and runs 'kamcmd tls.reload' when finished.
Our tls.cfg looks like this:
```
[server:default]
method = TLSv1.2+
private_key = /etc/letsencrypt/live/hostname.de/privkey.pem
certificate = /etc/letsencrypt/live/hostname.de/fullchain.pem
ca_list = /etc/kamailio/ca_list.pem
ca_path = /etc/kamailio/ca_list.pem
crl = /etc/kamailio/combined.crl.pem
verify_certificate = yes
require_certificate = yes
[client:default]
verify_certificate = yes
require_certificate = yes
```
After testing a bit we found that every time tls.reload is executed Kamailio consumes a bit more memory which eventually leads to all the memory being consumed which leads to issues for our users.
See following example:
```
[0][root@edgar-dev:~]# while true ; do /usr/sbin/kamcmd tls.reload ; /usr/sbin/kamcmd core.shmmem ; sleep 1 ; done
Ok. TLS configuration reloaded.

### Troubleshooting
#### Reproduction
Everytime tls.reload is called the memory consumptions grows..
#### Debugging Data
<!--
If you got a core dump, use gdb to extract troubleshooting data - full backtrace,
local variables and the list of the code at the issue location.
gdb /path/to/kamailio /path/to/corefile
bt full
info locals
list
If you are familiar with gdb, feel free to attach more of what you consider to
be relevant.
-->
```
If you let me know what would be interesting for tracking this down, i am happy to provide logs/debugging data!
```
#### Log Messages
<!--
Check the syslog file and if there are relevant log messages printed by Kamailio, add them next, or attach to issue, or provide a link to download them (e.g., to a pastebin site).
-->
```
If you let me know what would be interesting for tracking this down, i am happy to provide logs/debugging data!
```
#### SIP Traffic
SIP doesnt seem to be relevant here
### Possible Solutions
Calling tls.reload less often or restart kamailio before memory is consumed ;)

### Description
It seems that the fixup_free_* functions are not getting called when used with:
```
static cmd_export_t cmds[] = {
{"acc_log_request", (cmd_function)w_acc_log_request, 1,
acc_fixup, free_acc_fixup,
ANY_ROUTE},
// ...
{0, 0, 0, 0, 0, 0}
};
static int free_acc_fixup(void **param, int param_no)
{
LM_CRIT("acc free fixup = %d\n", param_no);
if(*param) {
pkg_free(*param);
*param = 0;
}
return 0;
}
```
Nothing is getting logged from the function. Is this expected not to print in free_fixup due to the destruction of kamailio and the logging is not reliable?
I also used gdb and added some breakpoints in `fixup` and `free_fixup` functions in some other modules (file_out) and the breakpoint was only found in `fixup` but not in `free_fixup`.
When is the `free_fixup` supposed to be called, at kamailio destruction or after fixing it and before the main loop starts?
<!--
Explain what you did, what you expected to happen, and what actually happened.
-->
### Troubleshooting
#### Reproduction
<!--
If the issue can be reproduced, describe how it can be done.
-->
Use any module that has a custom (maybe also provided from core) `free_fixup` function, and monitor if `free_fixup` is called using debug mode.
#### Log Messages

Hello all
we are seeing these kind of logs in a Debian GNU/Linux 11 using kamailio 5.5.6

```
The kamailio instance we are using is receiving around 1500 calls per second in average when we do start seeing these errors more frequently
In this instance we are using multihomed
the listen address list is
``` children=14
socket_workers=1
listen=udp:[192.168.99.70:5081](http://192.168.99.70:5081/)
listen=udp:[192.168.99.81:5060](http://192.168.99.81:5060/)
listen=udp:[87.1.1.27:5060](http://87.1.1.27:5060/)
listen=tcp:[192.168.96.105:8095](http://192.168.96.105:8095/)
listen=tcp:[87.1.1.27:5060](http://87.1.1.27:5060/)
tcp_children=6
port=5060
```
We use the first worker only to perform the OPTIONS requests from the dispatcher module.
The sockets
listen=udp:[192.168.99.81:5060](http://192.168.99.81:5060/)
listen=udp:[87.1.1.27:5060](http://87.1.1.27:5060/)
are used to communicate both A and B legs
so when a message is received at [192.168.99.81:5060](http://192.168.99.81:5060/) we send it to [87.1.1.27:5060](http://87.1.1.27:5060/) and viceversa
We were using $fs variable before doing the t_relay() function.
This way is working, but when load increases, seems sometimes kamailio doesn't get the proper socket to forward the reply.
I think the errors mainly are related to responses which are being forwarded, like if the function get_sock_info_list was not able to retrieve the listen interfaces
we have tried to set in the onreply routes the commands
set_recv_socket("udp:[192.168.99.81:5060](http://192.168.99.81:5060/)");
set_send_socket("udp:[87.1.1.27:5060](http://87.1.1.27:5060/)"); (when reply goes from private to public domain)
and it seems it reduces the number of

But i honestly don't know why the

appear
```
We also tried to increase the kernel buffers rmem and wmem from 208KB (as we had by default) to 4MB
Do you know a reason which could cause these logs to appear?
Any setup that could mitigate them?
thanks a lot and regards

Hi There,
We found a situation where topos seems to break, let me explain... Assuming the following scenario:
```
Caller ---- Callee
A: ------INVITE-----> Record-Route:A.A.A.A, Record-Route:B.B.B.B
B: <-----200 OK------
C: <-----INVITE------ Route: A.A.A.A, B.B.B.B
D: ------200 OK-----> Record-Route:B.B.B.B, Record-Route:A.A.A.A (reversed order)
E: <======INVITE===== Route: B.B.B.B, A.A.A.A (wrong)
```
A and B establish the connection from caller to callee, and topos works fine.
C (re-INVITE from callee) sends the Route header according to the Record-Routes from the original INVITE (A)
D is the 200 OK sent from the caller to the first re-INVITE (C) coming from the callee, with the Record-Route headers reversed, because is the order in which the callee received them; and according to the RFC it's working as intended:
```
When a UAS responds to a request with a response that establishes a
dialog (such as a 2xx to INVITE), the UAS MUST copy all Record-Route
header field values from the request into the response (including the
URIs, URI parameters, and any Record-Route header field parameters,
whether they are known or unknown to the UAS) and MUST maintain the
order of those values.
[...]
[When a UAC receives a response...]
The route set MUST be set to the list of URIs in the Record-Route
header field from the response, taken in reverse order and preserving
all URI parameters.
```
E takes the Route order from the last 200 OK ignoring they are in reversed order and assuming the top one is the first one, when it should be the other way around, sending to an IP address not reachable from the callee. And I think here is the issue, topos should not update the path on the Record-Routes from a 200 OK but if it does, it should take the reverse order
When disabling topos, everything works fine, or with topos enabled, by setting rr_update=0 works for us, but what if there is a real path update, rr_update=0 wouldn't work for us anymore. The Kamailio version is 5.8.0-rc0
Let me know if you need more information.
Thanks a lot,
Javi

### Description
Hello, I am using ndb_redis module with TLS and redis-cluster. kamailio connects to the cluster endpoint when getting data, gets a 'MOVED' response and prints below error, it does not get data from the new host.
### Troubleshooting
I have verified that I can connect to the cluster endpoint and the host in 'MOVED' using redis-cli on the system that kamailio is running on. I tried to connect to a self hosted cluster without TLS, it works as expected. It also works as expected with TLS and a single redis host.
#### Reproduction
Connect to a redis-cluster over TLS
