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

Hi List
Can anyone give me an idea on how many TLS/TCP connections an opensips
server can handle? Not sure if this is a fair question even. Or does the
number depend rather on the operating system underneath? If so does
opensips impose any further limitations?
A bit background: all our SIP clients use TLS connections for security
reasons. The connections will be kept open using keep-alives once the
clients are registered. I've got a opensips 1.6.2+tls running in a
virtual machine (with Ubuntu 10.0.4), and the virtual machine runs on a
host that agains runs Ubuntu 10.0.4. I want to get an idea how many SIP
clients this server can support, as TLS is obviously more 'expensive'
than UDP.
Thanks very much in advance!
Yufei
