I'm gonna chime in with Brian here. In particular with regard to these
socket files, the two things I think are the most plausible causes are (a)
filesystem damage and (b) suddenly killing random processes, which prevents
them from cleaning up after themselves. By (a), I mean to include
block-level corruption, but I'm mainly talking about problems like library
version mismatches. In other words, a situation where the filesystem, as in
/usr, /bin, /lib, etc., is out of whack in some way. If this is happening,
it's probably in your KDE config files. In any case, I think (b) is the
most likely candidate.
It's probably possible for you to get KDE to run smoothly and efficiently,
but I don't think removing huge chunks of the KDE SC from your system is a
good approach, and the reason is a kind of embarrassing one to admit, as a
fan of KDE myself. KDE is a pretty tightly integrated system, and
unfortunately fragmented sections of different parts of the desktop system
constitute very uncommon use cases. This means that sometimes removing a
framework from KDE (like Akonadi or KWallet) results in unexpected
behavior, including runaway processes which eat up 100% of the CPU and
application crashes (I've experienced each once). Most distros make this a
little worse, too — by compiling in the most commonly used features, they
often make these frameworks hard dependencies for their packages, and/or
create those linking expectations that cause crashes when they're missing
or disabled.
The good news is that you most definitely still can get a responsive system
on KDE by configuring these services in as minimal a way as possible.
Disabling Strigi/Nepomuk and leaving Akonadi in place is truly no more a
burden on your system than it would bear with them removed. Keeping KWallet
enabled as a service and never using it should do fine (except for one
weird, now-fixed Amarok bug).
Here are the things I would look for next if I were you:
• how does a fresh KDE configuration perform and behave (expect the first
login to take extra time; measure by the second)
• runaway plasma widgets
• heavy/slow disk access (look for 'disk/wait' in KSysguard), which can be
the result of frequent access to slow filesystems (e.g., ntfs-3g),
background updates by your package manager, and frequent swapping to disk
• pulseaudio problems (which are thankfully less frequent these days)
