This one turned out to be caused by a miss configuration of mythtvsetup for that half of the card. I was having an unrelated problem where I kept getting the wrong channel recorded from the second tuner. I didn't realize that for both "cards" in the setup you are supposed to select "tuner 0". > > > 2005-09-27 18:58:47.937 Changing from None to RecordingOnly > > 2005-09-27 19:00:50.097 Starting Commercial Flagging for "Seinfeld" > > recorded from channel 1002 at Tue Sep 27 18:29:00 2005. > > 2005-09-27 19:00:52.525 New DB connection, total: 1 > > 2005-09-27 19:00:52.575 New DB connection, total: 2 > > > > 2005-09-27 19:29:56.175 Finished, 2 break(s) found. > > 2005-09-27 19:42:26.867 IOBOUND - blocking in ThreadedFileWriter::Write() > > 2005-09-27 19:42:29.770 IOBOUND - blocking in ThreadedFileWriter::Write() > > 2005-09-27 19:42:36.596 IOBOUND - blocking in ThreadedFileWriter::Write() > > 2005-09-27 19:44:29.603 IOBOUND - blocking in ThreadedFileWriter::Write() > > 2005-09-27 19:44:30.534 IOBOUND - blocking in ThreadedFileWriter::Write() > > 2005-09-27 19:44:30.934 IOBOUND - blocking in ThreadedFileWriter::Write() > > Killed > > livingroom mythrun # > > livingroom mythrun # > > Does this error only happen when the backend machine is under heavy > network load, or can it occur when only recording a single stream from > the frontend? > > > This is with mythtv version .18.1 installed on gentoo machines. > > > > Do you guys have any advice as to what is going on? > > Could be network related.

Anyways, I took your advice and moved the pvr-500 into my master backend machine. So far no backend crashes (12 hours and counting...). One other thing for anyone following that may read this, oddly when I moved the pvr500 into the master backend I suddenly got the "no sound on card 0" problem. I was running ivtv v .3.8. I upgraded to the latest svn version and that problem was fixed. I don't know why v .3.8 worked fine in my slave backend... Pretty weird. Thanks Paul
