Looking at those results after responding, I noticed I only have 5 okular instances open, the pdf reader (sadly I stay mired in pdf documentation often), when it's spawning 13 xclient sessions. I wonder if this is just being stupid is what's blowing it out somehow.
PDF's, another bit lf legacy windoze technology I wish would die. I hate adobe, but it's become defacto for doc standards when libreoffice vs. openoffice vs. microsith office stay in a pissing match with each other.

[X reaching a maximum number of clients is a problem] in that it

more and more these days. Am I like the only actual person to use
linux these days that this occurs with?
I've never seen this happen. What do you get when this is happening and you do "xlsclients | sort | uniq -c" ? I currently have 64 X clients running here. Most KDE things show up as 2 or 3 X clients. plasma-desktop shows up as 20. firefox shows up as 1.
Every now and then problem will piss me off royally as literally my pc won't be able to wake my monitors up out of dpms sleep because of this (presumably), thus I have to hard reboot. Odd part is when it freaks like this, even ssh'ing in from my laptop, killing some pids (ie. chrome|chromium I have an xargs script I keep to seek and destroy all), and it still won't wake then. I need add something to watch these...
After it did this the other day upon composition of the email, I killed the chrom*'s, and it's been a bit stable. xrestop was another that was recommended to watch, but by the time I hit that limit, even xrestop gives me the "max number of clients reached", even though a cli application...
Another way I know my system is almost ready to implode is waking up out of monitor sleep, expecting to see the simple-locker screen, rather I see a full desktop, unhidden, but I can't actually click on anything. Yeah, so much for privacy/security, but at least someone couldn't interact with it. It requires me to ctrl-alt-F1, switch to a tty, and back to F7 to see the locker again, unlock, and actually use my desktop. Seem another byproduct of xorg freaking out.
At the (working) moment...

I made a note on my desktop (dry erase pen + glass tabletop == best whiteboard ever) to check that next time it freaks out.
https://unix.stackexchange.com/questions/25273/what-is-the-max-number-of-x-clientsI've seen reports of this, stating it's a hard-coded thing in xorg
code, which I find entirely asinine
It probably seemed like a reasonable assumption back when the X11 protocol was designed that an X client would only make 1 connection to the server, and that having 256 or 512 X clients at once was enough. I don't have the Xorg source here so can't find where this is set, either.
File locks, or rather just open files, bad nomenclature on my part. Actually I mean to include a "k" after that, or 300,000 is what I see chrome wanting to use from a ulimit perspective. I've seen that open by chrome|chromium between them consume 300,000k+ files opened, mostly every tab calling hundreds of libs each they require. This was the first limit I started hitting, eventually having to bump up my ulimit counts in limits.conf to a higher (borderline absurd) number.
Chrome/Chromium that launches some 300 flocks on various things, and
blows out the 256/512 client count on xorg.
What did you mean by "flocks"? If Chrome creates a separate X client for every browser tab, that'd probably cause stupidity, but I could see it doing that. (Having fewer than 30 tabs open at any given time would fix that if it were the case.)
mb@host:~$ cat /etc/security/limits.conf | grep nofile
# - nofile - max number of open files
#* soft nofile 16384
* soft nofile 524288
#* hard nofile 32768
* hard nofile 786432
The commented bits were the old default ubuntu limits, and my updated, blown way the heck out of proportion limits for how I work with them. Either modern linux needs to accomodate ridiculous necessity of modern apps, or modern apps need to respect why those limits were set to what they were. Who is right? Who knows, start holy war.
Agreed. The file handler issue was the biggest issue, but both it and the xclientslimits, and maybe others are crippling my usability as I can't trust my desktop any longer. I constantly lose work as I'm scratching in a gedit window without autosaves when I have to reboot. I'm less worried about my fork-bombing my system as I watch for memory leaks, but rather these almost dumb limits considering modern apps ignore respectable limits in various components of linux are my biggest limiter.I have 3 chrome profiles open, some pdfs, libreoffice,
some chrome apps, some file manager windows (dolphin/kde), and not
much else. [...] am I the only person that really "uses" a linux
desktop to see these?
Obviously not if you found some other people complaining on a search engine. First thing to do is figure out which program is causing the stupidity. I was surprised to see 20 plasma-desktop clients here, because plasma applets are useless and I didn't think I had any of them running at all.
