Re: [mythtv-users] Minimum memory for myth system
I was running 128 and the os using the swap partition a fait bit of time, since memory is/was cheap I upgraded to 512. But then I was doing other stuff beyond myth as well...

Re: [mythtv-users] Minimum memory for myth system
I used to have 128 MB for headless backend only and it was not enough: I was getting bad recordings sometimes. Now I have 320MB and no problems.

As I said, I only have problems when mythfilldatabase is running, and when browsing my (rather large -- Antenna/Dish Network/Expressvu) channel list/looking for alternate airtimes. I assumed that the massive MySQL queries were causing MySQL to eat RAM and cause the kernel swap excessively, but I don't think I've actually checked into this.. .. I'll try and remember to take a look while it is running someday and see what's actually going on. My original message might have not been entirely clear though -- other than the circumstances I mention above, it runs without a hickup -- and the video (playback) only stutters when mythfilldatabase is running. -- Ian Trider [EMAIL PROTECTED] ___ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users

My production myth box only has 256MB of ram as well. Never had a single problem because of it.

Re: [mythtv-users] Minimum memory for myth system
> I am wondering if anyone knows what is the > recommended minimum memory configuration of a myth system. I started with 256 MB RAM, but the backend (0.16) hanged every 5 days. I then increased to 512 MB and the system has become much more stable (backend hangs maybe once per month). 0.17 and 0.18 might be more stable.
