Maybe we should consider (as future extension) the possibility to bundle
multiple UDP listeners on the same worker. In this case, we can have a
large number of listeners with a relatively small number of workers/
processes.

Hello!
No, there is no way to prevent OpenSIPS from opening connections for
each process. Did you try to start opensips with fewer workers, for
example just 1, or 3? Does it start properly?

Thank you Bogdan. I actually use: socket=udp:*:5060 in config file.
Is there a way to not open a process per interface, to not have 1200
or 600 workers? as I said in my previous email, I tried auto scaling
and it didn't work.
Also, I have increased MySQL max connections but it didn't fix
the problem - I wonder if anybody has experience with this...
Thanks!

Hi OpenSIPer,
With 600 interfaces (btw , have actually listed the 600 sockets into
the cfg or pointed the socket to the interface?) with 2 workers per
socket -> 1200 workers / processes. That means 1200 connections to
your DB server, which may be a bottle neck (by default, mysql
accepts around 100 simultaneous connections).
I suspect your mysql server cannot cope with the 1200 conn,
preventing OpenSIPS to properly start.

Hi all,
I have a machine with 600 subinterfaces. when I start opensips
with 2 udp workers per interface, it doesn't start and keeps
restarting.
First error message was about too many connections to Mysql which
I fixed by increasing max_connections, but now I am getting:
ERROR:db_mysql:db_mysql_new_connection: initial connect failed
ERROR:core:db_do_init: could not add connection to the pool
ERROR:sql_cacher:child_init: Cannot connect to SQL DB from child

ERROR:core:udp_start_processes: failed to send -1 status code
ERROR:db_mysql:db_mysql_connect: driver error(2002): Can't connect
to local MySQL server through socket '/var/lib/mysql/mysql.sock'
(11)
and:
ERROR:core:send_status_code: write(-1) failed (-1): 32, Broken pipe
ERROR:core:udp_start_processes: failed to send -1 status code
Any ideas how I can fix this?
Also, can I just limit number of opensips forked processes, to run
just a certain number process instead of x numbers per interface?
I tried using auto_scaling but it did not help. in my
opensips.conf, I have:
socket=udp:*:5060
and adding an autoscaling profile in front of it seems to limit
the processes per interface again, not all...
Any help is appreciated.
Thanks!
