Still having problems with host name resolution

Hi,

I posted a message in this group in June in which I reported my
observation of Opera being unable to resolve any host names after
running it for about 9 hours. This problem is still not solved, and I
hope I can come up with a new theory and some more information which
can hopefully help to solve this problem.

I found that in our network at work the name server tends to stop
working every now and then. In such cases the behaviour is a bit like
what happens when you try to reach a service which is behind a
firewall - the client hangs until it gets a time out. Somehow this
seemed to always happen in the afternoon back then, but now it seems
to happen more often.

It looks to me as if Opera does not recover from this temporary
failure. Even after the name server has started workin again, with
every page you try to open you'll get a "looking up host name ..." in
the status bar, but you never (or at least not in a time which I was
ready to wait) get the host name resolved. The only thing which helps
in this case is restarting Opera.

Unfortunately I do not have a name server under my control with which
I can enforce the above temporary failure, but maybe anyone out there
can tell me whether my assumption above is too far-fetched to be true?
In any case I do have this problem and I have it almost every day.

Any hint?

Cheers,

Martin

Sounds like a theory that could be worth putting into a bug report.
