number of websocket connections

[swuy]

Hello!
I have kamailio installed as a part of kazoo server (kamailio server and server with other apps) with enabled websocket role. As I see in .cfg file there is default restriction for connection from one IP - 50, so 51st client from the same IP address get 403 error. So

1. How can I see how many websocket connections from one IP I have? (Except log messages in kamailio.log)

2. Our kamailio work fine for week and a half, after that I see messages in kamailio log:
   "[Some_IP_address] is at the maximum allowable sockets per IP, rejecting request for another websocket"

I checked connections from OS and saw that there is one connection not fifty.
lsof -ni TCP:8080 | grep [Some_IP_address]
kamailio 30673 kamailio 132u IPv4 4667683 0t0 TCP [Some_IP_address]:webcache->[Some_IP_address]:57688 (ESTABLISHED)

After restarting kamailio all work fine for another week and a half and repeat.
Is it some bug?

Hi,

"kamctl fifo ws.dump" shows you all websocket connections kamailio knows
about.

The point 2) seems to be specific to Kazoo configuration (as I searched for the log message on the web and pointed there), so it is not inside kamailio code but in that config file you are using. On a quick look, there is a counter of connections stored in a hash table that might not be properly managed. You have to address the issue to kazoo project.
