[OpenSIPS-Users] How many TLS connections can an opensips server handle?

[Bogdan-Andrei Iancu]

Hi Yufei,

OpenSIPS has a core paramter limiting the number of TCP connection (note 
that a TLS conn is counted also as TCP conn).  See the 
tcp_max_connections global param. The default value is 2048.  Of course, 
you can change it from the script.

Also take note about the system limitations.

Regards,
Bogdan
