Any ideas? First, questions like this belong on the FreeBSD-Questions list, not hackers. Anyhow, it's not possible to test memory using a PC. The only way to do it is with an expensive piece of test equipment. The return from Checkit is only good for complete failures; any other indication isn't worth anything at all. I mean that -- checkit is worthless to catch anything but gross memory errors. FreeBSD (or really any other unix) works a PC's memory far harder than any DOS or Windows based application, so the chances really are that your friend has a memory problem. What he has to do is take it back to his vendor and really insist on new memory. There isn't any software problem like he's talking about. This kind of thing is seen quite a bit among folks new to Unix ... I'm not guessing here, your friend's complaint is common, and if he wants to run FreeBSD, he's going to have to get the problem fixed. Under Windows 95, heck, it reboots of it's own accord so often, you don't realize that some percentage of those reboots are hardware faults.
