What exactly do you mean with "interrupt handler calls"? The timers?
They should *not* be called from an interrupt level: the core code of
lwIP may only be accessed from one context at a time!
If you obeyed this rule and still have problems, have a look at
wireshark packet traces and see if it reports errors in a packet. Also,
have a look at the stats (turn them on in lwipopts.h if not already
done) and find out whether there are packets dropped.
