Hi,
We tried to send more than 250 bytes in udp raw client socket, the
udp_send is giving succeess and server is not recived any data. is there
any data limitation for send and receive data. here i have attached log
PFA. the poolsize configration is bellow
#define PBUF_POOL_SIZE 100
#define PBUF_POOL_BUFSIZE 1500
please suggest us to how to move forward
thanks

I would recommend increasing the number of pbufs (PBUF_POOL_SIZE) and
the
size of the heap (MEM_SIZE) and see if your system runs longer? If
so, that
would imply you have a resource issue that you can look for? If not,
then
the problem is probably someplace else?

If this is your actual code, then you have a HUGE BUG right here! You
are
trying to set 'pbuffer->next' BEFORE pbuffer has a valid pointer.
That
can't be good! :o) (I'm surprised your compiler didn't warn you
that
you're using a variable before it has been initialized?!?)

Furthermore pbuffer->len and pbuffer->tot_len are already set by
pbuf_alloc... overriding them can't be good... you must take time to
understand how lwIP chained pbuf should be handled. I am confident you
are leaking pbufs here as well as a buffer overflow.
