Crashed today (Saturday afternoon, no particular activity that I can

Rebooted (hate that) -- *seems* to be OK; hardware seems OK (LAN eth cards
listening 192.168.0.30, 31, 32, 33.) Nothing else in logs -- access shows
average use.
We'll never know now.
Thank you (and Curtis, see below.) Most probably agree, but I'm still
looking...
If this happens again you'll need to employ tools like "sudo netstat -anp"
to find the process that has bound to port 80.
In fact, it was by running "# netstat -natp" that I found one eth card was
down (and the rather problematic Ubuntu ifup|down didn't work, that's why I
ended up "# shutdown -r".) The three other cards were OK, but the "normal"
"tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN 1682/apache2" was missing.
I'm still trying to understand "[mpm_prefork:notice] ... AH00171: Graceful
restart requested, doing restart" -- nobody was in the $workplace, only I
have ssh, so who/what "requested"? If it was a hardware failure (not
obvious even for a single card), does Apache automagically try a graceful
restart? -- even if three cards still showed "tcp 0 0 192.168.0.30|31|32:53
0.0.0.0:* LISTEN 1412/named"? -- and what's the "(98)Address already in use"?

It didn't fully go away. Some process was still there. Was it running fast

No -- cgid was "enabled" (not fcgid), and nothing "php" (I'm a tad
