I guess that dillo creates socket connection too often. Ok good. I'm working on a connection limit right now and hope to have something to test soon. Thanks for the continuous testing, Johannes

Yes, I see the same error messages with above combination, so definitely this is communication problem between dillo and my local proxy. I guess that dillo creates socket connection too often.

Ok, could you please try this combination: - TCP_NODELAY not included (e.g. hg up 239f9fc6c313) - cookies disabled - proxy is used My guess is that this combination also shows the problem, but of course we need to verify this.

Now I tried - cookie is enabled - TCP_NODELAY is included - no proxy is used Then I don't any see error message. So the problem seems to be communication between dillo and my local proxy.

I feel I see more error messages by this change. Is this without TCP_NODELAY? If so it would indicate that the real problem is the massive number of connections dillo is establishing if there are man images on a page and some servers / proxies don't like it. We probabely need to look at the experimental patch Jorge had posted here: http://lists.auriga.wearlab.de/pipermail/dillo-dev/2009-August/006778.html Cheers, Johannes

Could you try with cookies disabled and a dillo version before the TCP_NODELAY change? I remember that we once wanted to limit concurrent connections to a reasonable number and maybe the slow DPI communication is just doing that. So I suspect that without cookies even the version without TCP_NODELAY has issues - but that's just a wild guess. Regards, Johannes

There would be more pages but these are just examples. http://www.hatena.ne.jp/ http://f.hatena.ne.jp/hotfoto The first one doesn't contain so many images but relatively many and the second one contains lots of images. I don't think this is the site specific issue. Regards, furaisanjin
