Off the top of my head...
"Nagios" is ostensibly the report server and caching manager and "ganglia" IIRC is a page caching manager.
Actually neither of them are "caching managers" or have any direct role in caching. This isn't the forum to go into a detailed discussion of what they do mean, and a google search would do just as well to fill Carcharoth in, if he was actually interested, which he obviously isn't.
"Caching" basically just means keeping wiki pages in RAM so that things get fetched quickly - most people are not logged in so they get the same HTML and reuse the same CSS.
This is not particularly accurate either.
The main concept was that the error not only caused caching servers that were supposed to keep pages in RAM had to dump these pages into swap memory, but it affected a main caching node through which other nodes... do stuff... apparently. "Memcached" is the name of the caching software, or rather one of them, and the first one implemented here. IIRC it was first developed for /. (?),
I think you mean LiveJournal.
and kind of kept WP barely alive through the great traffic growth spurts of 04 and 05.
I looked up "scap" and still dunno what it is.

We don't make a big deal of it. Unlike deleting the main page, crashing the site is an easy mistake to make.
