Subject: no network to ip phones

Hello!


I run asterisk on x86 server , with kernel 2.6.39 all is OK, but with 3.0.38
and 3.0.39 after some time server lost connections to sip phones:

[Aug 2 15:02:51] WARNING[5790]: chan_sip.c:3392 __sip_xmit: sip_xmit of
0x9bd88f8 (len 548) to 192.168.26.116:5060 returned -2: Network is down

ping says the same, but other hosts work OK (from any other networks), only sip
phones are affected.

interfaces:

[root@...erisk ~]# ifconfig

default gateway is on eth0, i.e. not tagged.

hardware:
