Media is on a NAS box. NFS share. I discussed this problem in the amarok forum: http://forum.kde.org/viewtopic.php?f=115&t=98855 and an admin had this to say: "Based upon that strace output I believe it may either be in the process of attempting to close - or one of it's children may be in the process of doing so." strace output ends with: sendmsg(3, {msg_name(0)=NULL, msg_iov(2)=[{"l\1\0\1\23\0\0\0\2\0\0\0\177\0\0\0\1\1o\0\25\0\0\0/org/fre"..., 144}, {"\16\0\0\0org.kde.amarok\0", 19}], msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 163 poll([{fd=3, events=POLLIN}], 1, 25000) = 1 ([{fd=3, revents=POLLIN}]) recvmsg(3, {msg_name(0)=NULL, msg_iov(1)=[{"l\2\1\1\4\0\0\0\3\0\0\0=\0\0\0\6\1s\0\6\0\0\0:1.346\0\0"..., 2048}], msg_controllen=0, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 84 recvmsg(3, 0x7fffaff2db50, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource temporarily unavailable) sendmsg(3, {msg_name(0)=NULL, msg_iov(2)=[{"l\1\0\1+\0\0\0\3\0\0\0\202\0\0\0\1\1o\0\20\0\0\0/MainApp"..., 152}, {"\0\0\0\0#\0\0\0\0\0\0\17/home/earquilla\0\0\0\1\377"..., 43}], msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 195 poll([{fd=3, events=POLLIN}], 1, -1) = ?

Reproducible: Always Steps to Reproduce: 1. Log into KDE 2. Open amarok 3. Wait thirty seconds to a minute Actual Results: Program is completely unresponsive. If the amarok window is open and I try to close it by clicking the "X" at the top right, eventually it will tell me amarok is unresponsive and I can kill the program. If the amarok window is not open, clicking on the icon in my system tray does not do anything. Right clicking on the icon results in a delay of 10 seconds before any options pop up, but no matter what I click nothing happens. Quit, play, configure amarok, nothing happens. Expected Results: I would like amarok to not hang. My NFS share works perfectly fine otherwise. XBMC and VLC have no problems whatsoever playing the music. I have a separate NFS share for videos, and those work perfectly too. Also, Clementine has no problems playing my music and never hangs.
A complete backtrace would be really nice to have, please see also http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports how to get it with gdb. What we need is the part after the bt command.
Any news about this?
To get this backtrace I changed my CFLAGS from CFLAGS="-march=corei7-avx -O2 -pipe" to CFLAGS="-march=corei7-avx -O1 -ggdb" I also added the line FEATURES="splitdebug" I reinstalled amarok with the following USE flags: USE="cdda embedded opengl semantic-desktop utils -daap -debug -ipod -lastfm -mp3tunes -mtp -ofa" The following is the backtrace ~ $ gdb amarok GNU gdb (Gentoo 7.3.1 p2) 7.3.1 Copyright (C) 2011 Free Software Foundation, Inc.

If it matters, I noticed that right when it freezes, in the lower left hand corner it says "Scanning music". It is immediate: when that message appears it is immediately unresponsive. This is odd because I can manually click Tools->Update Collection and it will NOT freeze amarok. Yet when the message "Scanning music" comes up on its own, that is the single indicator that amarok will no longer be responsive.
That doesn't look like a crash in Amarok. Could you please install the missing debugging symbols for Qt, libfam and KDE, and when it freezes, run a full backtrace, e.g. the command is: thread apply all bt See also http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_when_an_uncaught_exception_is_causing_a_crash
i put the debug use flag into my /etc/make.conf file and tried to emerge amarok, kdelibs, qt-core, phonon-kde, qt-gui, and glib, but that results in a complete mess of package conflicts that i have no idea how to resolve. i'm a simple user, no package maintainer or developer. **************************************************************************************************************** Calculating dependencies... done!

That does still not look like an Amarok problem, more like a Qt or KDE one. But you should make sure your installation has no packaging conflicts, especially the kdelibs and qtlibs should be up-to-date, else running Amarok properly might be a problem.
Everything should be up to date. I'm running KDE 4.9.3 as well as Amarok 2.6.0. Both of these are "unstable" according to Gentoo- not sure how much more up to date I can get. I regularly update my entire system. I don't know why it took me so long to think of this- since I realized Amarok freezes right after it says "Scanning music", I simply unchecked "Watch folders for changes" in Settings->Configure amarok. It's actually working now! I got through an entire song and it moved to the next song for the first time.
Everything is working great now. If the issue pops up again I will update. Any ideas what could be causing this? Why would "Watch folders for changes" cause amarok to hang, while manually updating the collection does not?
Thank you for the feedback. This makes sense, as monitoring network shares for folder changes is not a good idea.

yep, that's the one (I couldn't find). thanks.
