Something is seriously wrong. "Address resolution queue is full" is just a warning. Either ntop saw too many new hosts to queue up all at once or your DNS resolution isn't working. Either way, it won't break things too badly.
But the other two messages, "Error: bad magic number" and "Error: wrong bucketIdx /160.92 (expected=4535/real=0)" are usually signs of serious memory problems. And trapping these are difficult - by the time ntop recognizes the problem, the damage was done long before. If memory is corrupted, then when it finally dies, that's also probably just a side effect, so gdb won't help. Nothing obvious jumps out - debugging these type of problems usually isn't a pretty.
