David,I hope you are also calling all other lwIP functions from the very same ISR you are calling tcp_tmr()... which you shouldn't be calling but sys_check_timeouts() instead; and as frequently as possible (like at the head of the main loop and no calls from ISRs...) Unless you have the resources to avoid reentrancy on non-reentrant lwIP functions, of course.
