Greetings,

I have two Machines with Kamailio in a High Availability  (HA) configuration. Both machines are active and processing calls and both have one HA IP that can jump to the other machine in case of failure.

I also have probing for NAPs configured with each IP as the socket. 

So, in each machine i have this configuration : 

listen=udp:HA_Address1

listen=udp:HA_Address2

NAP 1 being probed from socket HA_Address1

NAP 1 being probed from socket HA_Address2

I also have /proc/sys/net/ipv4/ip_nonlocal_bind with value 1.

Everything works correctly with this configuration. However when the probing is sent for the NAP' my logs get filled with the same error messages.

udp_send(): sendto(sock, buf: 0x7f2d4c91fa18, len: 340, 0, dst: (xxx.xxx.xxx.xxx:xxx), tolen: 16) - err: Invalid argument (22)

CRITICAL: <core> [core/udp_server.c:602]: udp_send(): invalid sendtoparameters#012one possible reason is the server is bound to localhost and#012attempts to send to the net

ERROR: tm [../../core/forward.h:219]: msg_send_buffer(): udp_send failed

The error happens because it is trying to probe a NAP using a socket that isn't active at the moment in the machine.

Is there a way for this error not to be logged or be disabled without reducing Log Level to suppress CRITICAL errors?

I think this is a standard High Availability configuration. Is there some setting that can disable this kind of errors?

Best Regards,
