I can confirm this with Akregator 1.3.3. For every topic I click in my feeds, akregator leaves "kfmclient openURL ..."-type processes. I use firefox as an external browser. Finally, it ends up with "too many open files" error in KDE (4.1.3) and I have to solve this by killing all kfmclient-processes. Here is an example from my working machine (shows kfmclient processes with links, I have clicked on to open in external browser (firefox)): dotcoder@dotcoder ~ $ ps ax|grep kfmclient 6334 ? S 0:00 /usr/bin/kfmclient openURL http://obso1337.org/hci/kde/SLUG_Meeting_19_Nov_2008.pdf 6347 ? S 0:00 /usr/bin/kfmclient openURL http://aseigo.blogspot.com/2008/11/plasma-systray-42.html 6443 ?

I have set my browser to firefox, and currently Akregator has left 16 of these processes around. Also, in one case recently, a leftover kfmclient process was holding one of my ALSA sound devices open, and nothing else, neither KDE binaries nor non-KDE, could produce sound until I had killed the kfmclient job. It seems as if the kfmclient starts up holding at least some of the open file descriptors of the process that launched it. I was on a video call/chat in Skype, and clicked a link in the chat window. The kfmclient that was created wound up holding the /dev/video device. When I later started Skype again, it was unable to access the camera for a video call because the kfmclient from hours earlier was still alive and holding that device open.

Yes, it doesn't close any fds, it can be verified using lsof. 4.2.1: still here, btw. I can confirm this issue too. Akregator opens a feed in firefox (which is set as the default browser. The kfmclient process then doesn't terminate. I attached to one of them using gdb and got this backtrace. #0 0xb7f37424 in __kernel_vsyscall () #1 0x4f515e51 in select () from /lib/libc.so.6 #2 0x4160cfb0 in QEventDispatcherUNIX::select (this=<value optimized out>, nfds=<value optimized out>, readfds=<value optimized out>, writefds=<value optimized out>, exceptfds=<value optimized out>, timeout=<value optimized out>) at kernel/qeventdispatcher_unix.cpp:608 #3 0x42856f93 in QEventDispatcherX11::select (this=<value optimized out>, nfds=<value optimized out>, readfds=<value optimized out>, writefds=Could not find the frame base for "QEventDispatcherX11::select(int, fd_set*, fd_set*, fd_set*, timeval*)". ) at kernel/qeventdispatcher_x11.cpp:190 #4 0x4160dde4 in QEventDispatcherUNIXPrivate::doSelect (this=<value optimized out>, flags=<value optimized out>, timeout=<value optimized out>) at kernel/qeventdispatcher_unix.cpp:172 #5 0x4160e2b9 in QEventDispatcherUNIX::processEvents (this=<value optimized out>, flags=<value optimized out>) at kernel/qeventdispatcher_unix.cpp:895 #6 0x42857193 in QEventDispatcherX11::processEvents (this=<value optimized out>, flags=<value optimized out>) at kernel/qeventdispatcher_x11.cpp:154 #7 0x415e54fd in QEventLoop::processEvents (this=<value optimized out>, flags=<value optimized out>) at kernel/qeventloop.cpp:149 #8 0x415e5690 in QEventLoop::exec (this=<value optimized out>, flags=Could not find the frame base for "QEventLoop::exec(QFlags<QEventLoop::ProcessEventsFlag>)". ) at kernel/qeventloop.cpp:196 #9 0x415e75f6 in QCoreApplication::exec () at kernel/qcoreapplication.cpp:851 #10 0x427d3547 in QApplication::exec () at kernel/qapplication.cpp:3337 #11 0x411949b4 in ClientApp::createNewWindow (url=<value optimized out>, newTab=<value optimized out>, tempFile=<value optimized out>, mimetype=<value optimized out>) at /tmp/portage/kde-base/konqueror-4.2.1-r1/work/konqueror-4.2.1/konqueror/client/kfmclient.cpp:345 #12 0x4119585c in ClientApp::doIt () at /tmp/portage/kde-base/konqueror-4.2.1-r1/work/konqueror-4.2.1/konqueror/client/kfmclient.cpp:523 #13 0x411969f0 in kdemain (argc=<value optimized out>, argv=<value optimized out>) at /tmp/portage/kde-base/konqueror-4.2.1-r1/work/konqueror-4.2.1/konqueror/client/kfmclient.cpp:140 #14 0x080487b2 in main (argc=0x4008108, argv=0x0) at /tmp/portage/kde-base/konqueror-4.2.1-r1/work/konqueror_build/konqueror/client/kfmclient_dummy.cpp:3 If you need more (such as the actual function parameters), let me know and I'll try and build a more debugging friendly binary and test it. I guess i have the same problem. I'm using firefox as default browser and i have lot (now : 36, but sometimes a lot more) kfmclient (as seen by 'pidof kfmclient | wc -w'). It even go as far as i can't start any X client, if i try in a konsole, i have a message saying that the maximum number of client is reached (i dont have the exact message here, sorry). Killing kfmclient's solve this problem. I have had this problem for very long, probably at least from KDE 4.1.0 *** Bug 182497 has been marked as a duplicate of this bug. *** I just notice this report. I had opened a bug for this problem in january (see bug 182497), so I marked mine as duplicate of this one. I can confirm it happens with akregator but I have noticed it with web shortcut (see my bug) in krunner too. I get it if I set something else than default browser (konqueror) in systemsettings (eg: arora or firefox) People who encounter this bug should vote to confirm it *** This bug has been confirmed by popular vote. *** SVN commit 993295 by pradeepto: -- kfmclient openUrl doesn't quit when using !konqueror ( fix using KGlobal::setAllowQuit(), thanks to Will Stephenson ;) ) BUG:171185 M +1 -0 kfmclient.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=993295 Confirmed, I no longer see the bad behaviour in a checkout of svn revision 994816. *** Bug 194883 has been marked as a duplicate of this bug. *** SVN commit 996912 by teve: Backported Pradeepto's commit r993295 to 4.3 branch CCBUG:171185 M +1 -0 kfmclient.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=996912 |
