The two directories are configured on both machines. I have a frontend running and while watching live tv switch the input between the two backends. The master backend segfaults regularly (but not every time). Running atrpms mythtv-backend-0.21-189.fc8 (Update to latest svn fixes (17421)) on fedora 9 x86 64bit. Slavebackend runs the same version, but is fedora 7 x86 32bit. backtrace: #0 PlaybackSock::SendReceiveStringList (this=0x0, strlist=@0x7fff7d92f290) at playbacksock.cpp:66 66 sock->Lock(); (gdb) bt #0 PlaybackSock::SendReceiveStringList (this=0x0, strlist=@0x7fff7d92f290) at playbacksock.cpp:66 #1 0x000000000049014b in PlaybackSock::SetNextLiveTVDir (this=0x0, capturecardnum=, dir=@0x7fff7d92f330) at playbacksock.cpp:336 #2 0x000000000042ee33 in EncoderLink::SetNextLiveTVDir (this=0x1145b90, dir=) at encoderlink.cpp:612 #3 0x00000000004b2ea0 in Scheduler::GetNextLiveTVDir (this=, cardid=4) at scheduler.cpp:3261 #4 0x000000000046dcba in MainServer::customEvent (this=0x7fb76800df50, e=0x7fb7680144f0) at mainserver.cpp:699 #5 0x00000030ffb63396 in QObject::event () from /usr/lib64/qt-3.3/lib/libqt-mt.so.3 #6 0x00000030ffb02b75 in QApplication::internalNotify () from /usr/lib64/qt-3.3/lib/libqt-mt.so.3 #7 0x00000030ffb03e40 in QApplication::notify () from /usr/lib64/qt-3.3/lib/libqt-mt.so.3 #8 0x00000030ffb039a9 in QApplication::sendPostedEvents () from /usr/lib64/qt-3.3/lib/libqt-mt.so.3 #9 0x00000030ffab0c9c in QEventLoop::processEvents () from /usr/lib64/qt-3.3/lib/libqt-mt.so.3 #10 0x00000030ffb1a321 in QEventLoop::enterLoop () from /usr/lib64/qt-3.3/lib/libqt-mt.so.3 #11 0x00000030ffb1a202 in QEventLoop::exec () from /usr/lib64/qt-3.3/lib/libqt-mt.so.3 #12 0x000000000044eacc in main (argc=7, argv=) at main.cpp:978 #13 0x0000003269a1e074 in __libc_start_main () from /lib64/libc.so.6 #14 0x0000000000413789 in _start () best regards, Florian Nierhaus ",defect,closed,major,0.21.1,mythtv,0.21-fixes,high,invalid,,Axel.Thimm@…,0
