Version: (using KDE 4.1.1) OS: Linux Installed from: SuSE RPMs I'm not sure whether this is a konqueror or kio_http issue. To reproduce it, you have to enable "open new links in new tab" and "open new external URLs in existing konqueror instance". Now open several instances of konqueror with some webpages and click on some links in emails, which results in other konqueror instances. Now wait ~10 minutes, maybe a few more. After that click on links in those konqueror instances. They will fail with: error, could not start http process.
When this happens I see the "restore session" often too, so there might be some connection.
A good way to reproduce this is to open links from within kontact/kmail, which almost always trigger a multiple "restore session dialogue" and kill other instances of konqueror.
Ah ha! So THAT's what's causing this. Very frustrating when my long-running Konqueror windows cease being able to communicate with KIO because I've been using other Konqueror instances on other desktops. Confirming this bug on Gentoo. $ uname -a Linux Crushinator 2.6.25-gentoo-r7 #2 SMP Mon Oct 20 11:41:48 EDT 2008 x86_64 Intel(R) Core(TM)2 Quad CPU Q6600 @ 2.40GHz GenuineIntel GNU/Linux $ gcc --version | head -n1 gcc (Gentoo 4.3.2 p1.1) 4.3.2 $ equery list -f 'kde-base/(kdelibs|konqueror|kio)' [ Searching for package '(kdelibs|konqueror|kio)' in 'kde-base' among: ] * installed packages [I--] [ ~] kde-base/kdebase-kioslaves-4.1.2 (4.1) [I--] [ ~] kde-base/kdelibs-4.1.2-r1 (4.1) [I--] [ ~] kde-base/kdemultimedia-kioslaves-4.1.2 (4.1) [I--] [ ~] kde-base/kioclient-4.1.2 (4.1) [I--] [ ~] kde-base/konqueror-4.1.2 (4.1) P.S. How ironic! When I went to hit "Commit" on this bug comment, I was hit by this very bug! Had to restart Konqueror and come back here to post.

Please test again in trunk or when 4.2 is out. I've had similar problems related to session management and they were fixed at some point.
I haven't experienced this bug since upgrading to KDE 4.1.3.
I'm now on the 4.1.96 pre-release, and I have not seen this bug in a long time. I do occasionally see another bug when I'm browsing pages rapidly and I get a nearly immediate time-out when clicking a link (but then hitting Reload gives it to me), but that I think is an entirely different problem, likely due to pooling and reusing connections poorly.
I did not encounter it anymore either using KDE 4.2
