asterisk users - Mar 2009 - Asterisk talking to mysql database through odbc

Hi,
    I have 2 instances of asterisk running and taking to common mysql
database via ODBC connection.

I am facing some issue while running bulk call (around 100 calls at a
time),like few call gets error out of 100, i am suspecting that SQL query is
failing and the error i get in one the call failure is ..

[*Mar 12 03:29:55] WARNING[27752] chan_sip.c: sip_xmit of 0xb76a27fc (len
446) to 114.105.116.121:26991 returned -1: Address family not supported by
protocol*

Anybody faced this issue...?

Also what's the significance of rtcachefriends=yes in sip.conf, if i enable
this error frequency reduces, but error occurs eventually.
