Hello,

I’m using the resolv standard library.

After resolving several names, it stops working.

The resolver simply hangs and does not provide a result.

I’m still trying to isolate the problem, but has anyone else  
experienced this?

Kind regards,  
Samuel

you might want to try using hijack or live console to see where it  
hangs. Could also try turning do\_not\_reverse\_lookup on.
