One of my machines is somewhat prone to "having a bad day", when it

Now that I've put on my pedant's hat, what I meant was that I very
occasionally get a normally-good program which segfaults. For other
programs such as firefox, occasional segfaults are par for the
course.
That really points to HW. I've been building a new system for a few days
now and noticing a lot of details. I have installed lm_sensors and
display info via a program not in BLFS called gkrellm.
When I built libreoffice, I told it to use all 4 processors on the i5. It
chugged along for almost two hours. Watching the temperatures on the
cores, they went from a normal 24C to about 50C when they went full out.
That's not a problem on my system as the warning threshold is 85C, but it
shows what can happen when the processor works hard. On marginal HW, this
can be a problem.
The same types of problems happen with flaky memory. One thing to try, as
was mentioned earlier on one of the support channels, is to remove and
reinsert all the memory SIMMs to ensure the connections are solid.
