[OpenSIPS-Users] opensips 1.11.7 tcp_send failed

Hi, all. I have a problem with TCP in opensips 1.11.7. All users are 
registered with tcp proto. Call flow: userA -> (tcp) opensips -> (udp) 
freeswitch -> (udp) opensips -> (tcp) userB.

When call is coming from FS I get error:

> Jun  3 11:53:57  ERROR:tm:msg_send: tcp_send failed
> Jun  3 11:53:57  ERROR:tm:t_forward_nonack: sending request failed
opensips.cfg contain tcp_no_new_conn_bflag = 6 and I'm setting this flag 
when INVITE is coming from FS.

Best regards,
Igor Pavlov
