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?!?)
