[mythtv-users] mythbackend crashes every 6-7 hours

[Rob Verduijn]

Hello,

Hunting for very obscure ram memmory flaws sounds like a ghost chase to me.
So I'll classify that one under gut feelings and assumptions and
therefore won't waste time on it.
(Even if I had any spare ram, which I don't)

But the valgrind suggestion sounds like a more reasoning aproach to me.
Do you have a link to a howto, because I'm not really familiar with valgrind.
I will get on it as soon as I figure out what valgrind is and how to use it.
