I bought a new additional 512MB DDR RAM yesterday.
After installing the RAM, I normally started up Fedore Core 2, Gnome, gkrellm, licq, terminal, mozilla and mldonkey.
The strange thing is that mldonkey (mlnet -daemon) was running, but I couldn't connect to it by telnet or www.
But before installing the RAM (and a new soundcard too) it always worked.
I also had a zombie process (netstat, that I did NOT use), which I never had before.
Now I removed the RAM, and mldonkey works again. So I suspect something is wrong with the new RAM.
I wanted to test it with memtest86-3.1a, but this always segfaults no matter if I have the new RAM installed or not.
Does anybody know a working memory test program or what the reason for this strange computer behaviour could be?
