<p>Karsten,</p>
<p>Thanks for your answer!</p>
<p>Out of your head, were there any significant changes in TCP/TLS
on 5.4 -> 5.5 change?<br>

<div>Hello!</div>
<div><br>
</div>
<div>Due to I still experience irregular Kamailio 5.4
crashes (like 1/month) related to SSL (using
websockets and SIPS) I'm wondering, could openSSL
upgrade change the situation?</div>
<div>As of now in CentOS 7 I have 1.0.2k version. <br>
</div>
<div><br>
</div>
<div>Does anyone have experience to fix crash-related to
TLS problems with openSSL upgrade?</div>
<div><br>
</div>
<div>Or maye some tuneup of TCP parameters can help
here?My current setup is quite simple:</div>
<div><br>
</div>
<div>children=4<br>
</div>
<div>enable_tls=yes<br>
tcp_accept_no_cl=yes<br>
tcp_connection_lifetime=600<br>
tcp_max_connections=998976 # 1000000 - 1024, so we're
leaving 1k for system reserve<br>
tls_max_connections=998976</div>
<div><br>
</div>
<div>Number of clients ~ 200 constantly connected to
websocket.<br>
