Both signed and unsigned ngx_[u]int_t has the same size, so that's 
more about preferable representation of numbers, not about 
correctness of the code.

In this particular case I think that %ui is better, as negative 
numbers shouldn't be here, and logging them with %ui will make 
them clearly visible as very big positive numbers.  It's also what 
will be used in the actual poll() syscall.

For future reference, please also take a look at the following
