Hello,

Since the introduction of glibc-2.1.94 into Woody I randomly get 
name-resolution failures. Not all applications seem to be affected equally, it 
seems that apt-get is having problems more often than other software but it's 
not limited to apt-get.

The problem appears to be completely random, and comes and goes. It occurs with 
both 2.2.x and 2.4.xtest kernels.

Name resolution never really fails for all sites; I might be perfectly able to 
resolve www.debian.org for instance, while totally unable to resolve 
ftp.uk.debian.org. And then after a while, perhaps ten minutes, perhaps more, 
sometimes less, it works again.

I have never seen this kind of problem until the glibc upgrade; name-resolution 
sometimes failes due to DNS weirdness of my provider but never in this way.


In case it's of any help, I attached ltrace and strace output for telnet.


Does anyone experience similar problems? Or have any clues as to what I can do 
to fix the problem or debug it?
I can't remember having seen any notices of it on the glibc-mailing list, but 
I'm not subscribed to it and don't follow it religiously.


Any help is appreciated!

regards,

--Tim
