If I comment the pxRxBuffer = netconn_recv( pxNetCon ); line and

What is causing that and how do i fix it so i can recive multiple

Looks OK to me at first glance, so not sure why it's not working. Do
you do the netconn_write() straight after that loop?
It sounds like you might be running out of buffer space or something
like that. I would suggest turning on the LWIP_DEBUG code and comparing
the output from the case where it works to the case where it doesn't.
The LWIP_STATS might also reveal what is failing.

Where do i set the buffer space?
When enabling debug i get a long list of compile errors.
src/lwip-1.3.0//src/core/tcp_out.c: In function 'tcp_write':
src/lwip-1.3.0//src/core/tcp_out.c:97: error: expected ')' before 'U16_F'
src/lwip-1.3.0//src/core/tcp_out.c: In function 'tcp_enqueue':
src/lwip-1.3.0//src/core/tcp_out.c:141: error: expected ')' before 'U16_F'
so no debug info at the moment.
