Too much?
Am I trying to do too much on my FE/BE combo box? I found I had problems
when I tried to run Kodi on it so I stopped doing that. Recent problems
occur since I've been using Netflix over Chromium and Zoom. My initial
thoughts were that a Quad core AMD with 16 gigs of RAM should do anything I
wanted, but now I'm scratching my head. I only use the one FE so I thought
a combo would be best, Should I keep the BE separate, and use a second box
for all else?
TIA Daryl

That should be fine. Running Kodi as well should be fine. My massive
MythTV database works well in just 8 Gibytes of RAM and an 8 year old
quad core AMD. You can use htop to see how much RAM and swap space is
being used and how much CPU. But you should check and make sure that
you have not been sold hard drives that are shingled - that causes
endless problems if you use them like normal drives.

L200 are shingled, I don't see L200 on mine, it looks like ACA100 (they're
still installed) and have worked well for some time.
now my database is corrupt again, mythfilldatabase wont run, saying
"Incorrect key file for table 'videosource'; try to repair it" I've run
optimize_db.pl, I'malmost ready to get out a big hammer!

the screen went black last night as I was responding, I think I will
rebuild from scratch, new database and all.

Daryl,

This really does sound like a hardware issue outside of the disks.

Have you tried running memtest86 on that machine for a few hours?

Yes,

When Intel chips overheat, the ramp down on CPU speeds, when AMD overheats, they cut power.

Yes, I have had that happen on my mother's old MythTV motherboard
recently. It needed the CPU fan cleaned. I find that with my AMD
processors I need to clean the CPU fan at least every six months,
otherwise the fan noise becomes nasty as it ramps up to try to cool
the CPU. When the CPU overheats, the entire PC shuts down instantly.

has two legs with 1 ide and 2 sata connectors each, of which only one works
reliably, so until amazon delivers i'm using an ide to sata converter and
limping along.(ROM, OS, and two storage drives) I've purged my system of
mysql 8 and mythtv, and when I try to reinstall I get these errors:

My system is rebuilt, with a clean install and a restored database,
avoiding the bad leg of the power supply. I'll breathe a lot easier when
the replacement arrives, Tuesday, they project. Many thanks to to the
developers and this community, Mythtv is the best by far!
