I've found memtest86 a less than reliable method for determining if memory modules are bad. On several systems I've repaired, memtest86 passed every time, but a kernel rebuild loop caused segfaults. Replace the ram, no more segfaults. IMHO unless you're testing a system using heavy I/O stressing, which really pushes the load on the masked areas of memory, you're not going to get a result. As for the possibility that the OP's problems stem from a badly configured client, that doesn't explain the gzip failure (more heavy I/O?), and the other posters have missed the original point that the lockup occurred *after* he'd already "finished the download". However, I do agree in general that both yum and up2date seem to have problems downloading - that apt doesn't seem to suffer from so much (very weird considering they all use the same Repos now - maybe it's a timeout setting). IME, random failures, known stable code causing crashes or lockups, and the classic - persistent Distro installation failure, all point to the same thing - bad ram chips (at least 90% of the time, about another 9% due to overheating or loose connections, and 1% due to factor "X"). - K.
