Matto: Restarting may be a cop-out solution, but if it fixes the problem, then the problem probably wasn't very interesting or worth more effort.

If in three weeks you have a problem of "this server has crashed twice in the past three weeks", then you have a problem that restarting won't solve, and you end up in a different place on the triage chart.

I'd also contrast that with my problem that, about once every four to six months, my laptop bluescreens a couple of times. I've spent a few hours in desultory attempts to diagnose the problem, including complete wipe-the-OS-and-reinstall cycles and serious hardware diagnotics but it's still there. With reasonable save habits, it costs me maybe three hours of work (worst case) when it hits, and I'll be using the laptop maybe a couple more years -- so, rough estimate of 12 hours total. It would take me a lot longer to really solve the problem, and in a couple of years the laptop will probably be worn out anyway.
