> Subject: UDP packets blocks

>
> Hi,
> I have a problem on receiving UDP packets on a WildFiremod board  
> with MCF5282 micro.
> I have a program like this:
>
> INT32 udpCallback(......)
> {
>       // if packet is a command, do work
> }
>
> int main(void)
> {
>       tcpip_init(0);
>      gUdp_socket = udp_getsocket(0,udpCallback,0);
>      udp_open(gUdp_socket,port);
>     while(1) tcp_tick();
> }

> My problem is that after a couple of time (about 3-4 minutes) that  
> program runs without receiving command packets, if I send it a  
> packet, it doesn't execute callback. Only after 3 or 4 received  
> packets it executes callback and process all packets received.  
> Packets are not lost, because when program "wakes-up", it process  
> all packets in the same order that it has received them.
> I think that buffer queue hangs for an unknown cause, and then re- 
> starts work in the right mode when buffer has more packets.
