Hi I have a mythbackend with the following configuration:<br>Asus P3CLS server motherboard<br>1ghz Pentium 3 processor<br>Integrated Intel 10/100 network card<br>4 IDE Maxtor 7200 udma 66 drives<br>256 rdram memory<br>No soundcard
<br>agp graphics card for troubleshooting not used for frontend<br>3 pcHDTV cards<br>2 Happaugge PVR 250<br><br>Running knoppmyth RD51 (it is supposed to be the leanest mythtv installation and is myth .19)<br><br>I have multiple frontends, connected via a cisco switch.
<br><br>For example one is the following:<br><br>MSI RS480mil<br>AMD 64 3200 Venice<br>Nvidia 5300 pcx <br>80 gig UDMA 100 IDE drive<br>1gig ddr667 dual channel memory<br>10/100/1000 integrated networking<br>Knoppmyth RD51
<br><br>I have a lot of issues with the frontends crashing. Locking up to the point I cannot SSH in or kill gdm. I have to physically reboot the machine. The Backend doesnt seem to crash. <br><br>In the logs I get alot of errors, that appear to be memory related. The backend has only 256 megs of memory but that is RDRAM.. I have read that Isaac uses 256 as the reference platform. I really don't want to get more memory for the backend because RDRAM is expensive and its a $250 guess to do that.
