[Serusers] Error using TCP

I'm using SER 0.9.3 with OpenBSD 3.7 amd64. Everything works correctly if I use normal UDP connections. Now I have to use a TCP connection (UDP is blocked in that network). Using ngrep I see SER receives the requests ma no reply is sent. The following errors are logged: Aug 23 12:48:06 eowyn /usr/local/sbin/ser[16406]: ERROR: send_fd: sendmsg failed on 19: Invalid argument Aug 23 12:48:06 eowyn /usr/local/sbin/ser[16406]: ERROR: send2child: send_fd failed Aug 23 12:48:06 eowyn /usr/local/sbin/ser[16406]: ERROR: tcp_main_loop: no children available So it seems that no TCP childrens are available but I can see them using "serctl ps": 0 10963 attendant 1 24595 fifo server 2 19807 receiver child=0 sock= 195.120.250.50:5060 3 24795 receiver child=1 sock= 195.120.250.50:5060 4 6812 receiver child=2 sock= 195.120.250.50:5060 5 27930 receiver child=3 sock= 195.120.250.50:5060 6 22186 timer 7 1034 tcp receiver 8 3296 tcp receiver 9 605 tcp receiver 10 15085 tcp receiver 11 18905 tcp main process What could be the problem?
