[boost] Some problems about singleton_pool

When using the "singleton_pool" to allocate the new space, I found there is
a limitation in this pool. If I want to allocate 16KB memory space,I can do
it by call 65503 times( about 1GB space has been used ). Then, I established
another singleton_pool object to allocate 1KB space ,this time I succeed
524255 times( about 500MB memory space). I want to know whether there is a
limitation in that?
thx.

ps : the sample codes:
typedef boost::singleton_pool<PieceMemoryPoolTag, UDP_BIG_BUFFER_SIZE+1>
BigPool;

void* BigMemPool::malloc(void)
{
    void *pbuf = BigPool::malloc();
    assert(pbuf);
    if (pbuf != NULL)
    {
        memset(pbuf, 0, UDP_BIG_BUFFER_SIZE+1);
        bigmalloctimes++;
        char str[128];
        sprintf_s(str, "BigMemPool::malloc %lu", bigmalloctimes);
    }
    return pbuf;
}
