### Description
* kamailio 5.6.1 on AlmaLinux 9 and OpenSSL 3.0.5
* Used tlsa to separate the OS version of OpenSSL (which is 3.0.1). The same issue happens
with the OS version of OpenSSL
* Generating TLS client traffic
* The issue will occur at about 25 conn/sec
* Multiple unpredicatable types of shm corruption
### Troubleshooting
* No issue with tlsa + OpenSSL 1.1.1q; the module can sustain 50 conn/sec up to 500 persistent connections.
#### Reproduction
1. Used kamailio configuration from the outbound module documentation; i.e., configure kamailio as a TLS edge proxy.
To isolate the registrar is another kamailio system
1. Use a SIP load tester to generate REGISTER traffic(Expires: 600) ; at the end of the REGISTER, keep the connection alive and reREGISTER at 300 secs.
1. Generate traffic at > 25 conn/sec (with < 25 conn/sec the test usually succeeds)
#### Debugging Data
BT in comments below
#### Log Messages
#### SIP Traffic
### Possible Solutions
### Additional Information
5.6.1
* **Operating System**:
AlmaLinux 9, with (OS) OpenSSL 3.0.1. I used tlsa + OpenSSL 3.0.5
