UDP and TCP are two totally separate protocols built on top of IP, so
there's (from the protocol point of view) no way they can influence each
other. What you're seeing looks like a misconfiguration or a bug in your
port or application. Normally, what you described should work with lwIP.

Following code sequence I use in my "UDP Thread" which will be woken
every 10ms:
/*******************************************************/
// allocate packet buffer
p = pbuf_alloc(PBUF_TRANSPORT, (1024 + 5) * sizeof(int), PBUF_RAM);
This does look a little strange: why do you allocate 10 Kilobytes as a
buffer? The udp raw API should only be able to send 1472 bytes per UDP
datagram/udp_send call (for an MTU of 1500). If you did not explicitly
take care of Jumbo Frames in your port, I would have expected such a
large datagram to be never transmitted.
