network stack assert failed

What steps will reproduce the problem?
1. include zrv.cmd.net.tst_srv in any template (I use nonvga with e1000)
2. embox>tst_srv
3. on host, do "echo -ne test | nc 10.0.2.16 7770" where your ip substituted

What is the expected output? What do you see instead?
Wait request...
