[mythtv-users] Suggestions for a stable backend

[EJS]

Hi there,

My backend works but it just isn't very stable.  It experiences two types of crashes relatively frequently (one every other day or so).  The first one is  a kernel dump that typically occurs when both of my tuners are recording at the same time- although not always.  The second type occurs when the whole box just freezes and won't respond to any keyboard/mouse input.  This one doesn't seem to be related to recording.

I had taken the kernel dump problem as far as I could.  It seems to have been introduced on 12.04, but i haven't seen any resolutions.  The second problem doesn't write anything to the log files so I am not sure how to even begin to debug.  

In any case, I'd love some suggestions or recommendations for a rock solid system.  Here is my current configuration:
Motherboard:GA-73PVM-S2H/GA-73PVM-S2H
CPU: Intel Core 2 Duo E8600 Wolfdale 3.33Ghz
Ram: 2GB
Tuners: 2  HVR-1250
Mythbuntu 12.04
Linux version 3.2.0-33-generic

mythbackend version: fixes/0.26 [v0.26.0-42-g10479af]

The backend also runs a SD front end that I use on occasion, but it mainly drives 2 zotac zbox HD frontends. I record perhaps 5-7 shows a week mostly HD QAM. I assume that this isn't considered very heavy usage.

Does anyone have any suggestions?  Is my hardware appropriate what what I am trying to run?  Do I need more ram or a faster cpu?  It took a lot of tweaking to get the 2 HVR-1250s to run. I like them because they are cheap but would a different card be more stable?  I had to install a special version of the motherboard bios to get the server to even recognize the second card without crashing.

Would upgrading myth or the os make any difference?  I am willing to buy new hardware if its needed, but I'd hate buy new components if the problem is really in the software. 

I know this is a relatively vague request, but I'd love some suggestions or even example configurations of stable systems similar to mine.

Thanks in advance!
