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

[yufei.tao]

Hi List Thank you very much Bogdan for the very helpful reply! Now seems
I'll need to find ways to increase the limitation of the max number of
allowed TCP connections for Ubuntu - for the VM that opensips runs on
and the host. I'll be very grateful if anyone would like to share their
experience on this. Thanks very much! Yufei Message: 2 Date: Thu, 03 Feb

Content-Type: text/plain; charset=ISO-8859-1; format=flowed 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 yufei.tao wrote:
