[Serdev] TCP problems

[Katty Xiong]

Hi Andrei,

When doing stress test (800CPS), I see several errors
in SER:

16(7297) msg_send: ERROR: tcp_send failed
16(7297) ERROR: tcp_blocking_connect: SO_ERROR (146)
Connection refused
16(7297) ERROR: tcpconn_connect: tcp_blocking_connect
failed
16(7297) ERROR: tcp_send: connet failed

The error consistently happens in one process, though
I have 8 TCP child proesses. Is there a workaround for
this error? 

Also you asked if I use one tcp connetion last time. I
assume the connection you mean is between UAC and SER.
Is that right? I notice SER and UAS always has one
connection whether we have one or 2 SIPp instance for
UAC. Is this tunable?

thanks,
Joy
