Hello! I am using FreeBSD-10/stable. We have a program at work that transmits = data via UDP. When I run several instances of this program simultaneously, after a few = seconds network stops working. If I login from console, I see some network daemons like ntpd, snmpd are = in "*udp" state. If I try to deal with network interface (ifconfig igb0 for instance), = ifconfig utility stuck in "L" state (Marks a process that is waiting to = acquire a lock.). I found the only way to fix that: reboot. What can be the cause for such a behaviour? Thanks.=
