For a while now on my Ubuntu 8.04 server (upgraded from 7.10) I've been getting segfaults in my dmesg, although have noticed no issues caused by them. It was built from untested parts I've had lying around for a while so the motherboard, cpu or ram could have issues although it's never crashed in the few months I've been using it. Here is a snippet from my current dmesg:
Code:

Is it worth bringing down my server and running memtest off a live cd? It has 3 sticks of ram (each 256mb) and I could definitely live without one or more of them (it's just a file server running samba, nfs and rtorrent).

Thanks in advance
