And btw, I bet this has already been fixed, a lot of deadlocks/hangs in aKode have been fixed recently. The only thing that stops me from using it right now is my streaming-mp3 addiction :) I'm using arts from NOW, so no fixes ... But I will use the mailinglist, thanks for the tip. Updated also kdemultimedia, and now it seems to work. Thanks. |
Version: (using KDE Devel) Installed from: Compiled sources Compiler: gcc (GCC) 3.2.3 OS: Linux Since a few weeks I have the problem that artsd stops when trying to play an ogg file (or probably any kind of sound - I don't know). The situation is, that I have a kmail filter action to play an ogg file. It works partly, that means: if I receive more mails, I hear the first few sounds playing, but then suddenly artsd hangs (blocks) which leads to a blocking kmail. As I have this very often (like now) I started gdb attached to artsd and get the following bt: (gdb) bt #0 0x4076abf1 in do_sigsuspend () from /lib/libc.so.6 #1 0x4076acb9 in sigsuspend () from /lib/libc.so.6 #2 0x40609278 in __pthread_wait_for_restart_signal () from /lib/libpthread.so.0 #3 0x40606564 in pthread_join () from /lib/libpthread.so.0 #4 0x409eb127 in aKode::FrameToStreamDecoder::halt (this=0x40a73f98) at frametostream_decoder.cpp:114 #5 0x409ea79e in ~StreamToFrameDecoder (this=0x40a741d8) at streamtoframe_decoder.cpp:53 #6 0x409d2cc6 in akodePlayObject_impl::halt (this=0x40a0d580) at akodePlayObject_impl.cpp:214 #7 0x409d304b in akodePlayObject_impl::readFrame (this=0x40a0d580) at akodePlayObject_impl.cpp:268 #8 0x409d3406 in akodePlayObject_impl::calculateBlock (this=0x40a0d580, count=512) at akodePlayObject_impl.cpp:326 #9 0x409d3945 in virtual thunk to akodePlayObject_impl::calculateBlock(unsigned long) () at akodePlayObject_impl.h:40 #10 0x40120958 in Arts::StdScheduleNode::gslProcess () from /opt/kde3/lib/libartsflow.so.1 #11 0x40196895 in master_process_locked_node () from /opt/kde3/lib/libartsflow.so.1 #12 0x40196b40 in master_process_flow () from /opt/kde3/lib/libartsflow.so.1 #13 0x40193df5 in gsl_engine_dispatch () from /opt/kde3/lib/libartsflow.so.1 #14 0x40125f4a in GslMainLoop::run () from /opt/kde3/lib/libartsflow.so.1 #15 0x40121dcc in Arts::StdScheduleNode::requireFlow () from /opt/kde3/lib/libartsflow.so.1 #16 0x4011f729 in Arts::Synth_PLAY_impl::needMore () from /opt/kde3/lib/libartsflow.so.1 #17 0x4011f761 in virtual thunk to Arts::Synth_PLAY_impl::needMore() () from /opt/kde3/lib/libartsflow.so.1 #18 0x401276cc in Arts::AudioSubSystem::handleIO () from /opt/kde3/lib/libartsflow.so.1 #19 0x4011f626 in Arts::Synth_PLAY_impl::notifyIO () from /opt/kde3/lib/libartsflow.so.1 #20 0x4011f6e9 in virtual thunk to Arts::Synth_PLAY_impl::notifyIO(int, int) () from /opt/kde3/lib/libartsflow.so.1 #21 0x40401b72 in Arts::StdIOManager::processOneEvent () from /opt/kde3/lib/libmcop.so.1 #22 0x40401fbb in Arts::StdIOManager::run () from /opt/kde3/lib/libmcop.so.1 #23 0x403ffc88 in Arts::Dispatcher::run () from /opt/kde3/lib/libmcop.so.1 #24 0x08063ee7 in main () (gdb) info threads 5 Thread 65540 (LWP 15452) 0x4076abf1 in do_sigsuspend () from /lib/libc.so.6 4 Thread 49155 (LWP 15445) 0x4076abf1 in do_sigsuspend () from /lib/libc.so.6 3 Thread 32770 (LWP 15438) 0x4076abf1 in do_sigsuspend () from /lib/libc.so.6 2 Thread 32769 (LWP 14408) 0x40819f32 in loser_poll () from /lib/libc.so.6 1 Thread 16384 (LWP 13939) 0x4076abf1 in do_sigsuspend () from /lib/libc.so.6 Doing an strace in this situation I get: strace -p 13939 Process 13939 attached - interrupt to quit --- SIGALRM (Alarm clock) @ 0 (0) --- times({tms_utime=455, tms_stime=123, tms_cutime=0, tms_cstime=0}) = 6119424 gettimeofday({1088153028, 777159}, NULL) = 0 times({tms_utime=455, tms_stime=123, tms_cutime=0, tms_cstime=0}) = 6119424 gettimeofday({1088153028, 777757}, NULL) = 0 rt_sigaction(SIGALRM, {0x4060cbc0, [ALRM], SA_RESTORER|SA_RESTART, 0x4076a988}, {0x4060cbc0, [ALRM], SA_RESTORER|SA_RESTART, 0x4076a988}, 8) = 0 sigreturn() = ?
