New files filling up /tmp: stdInFifo, stdOutFifo, stdErrFifo

After the Great vtown-->current/kde Rollout of Aught-Twenty, new files are accumulating in /tmp. Like Thunderbird's /tmp/ns*, a bad-form design flaw somewhere fails to clean up its temporary files in their class destructor. So far,
stdInFifo5NL
stdInFifoK3h
stdInFifobmp
stdInFifoyXg
with their matching stdOut and stdErr cohorts are accumulating, never purged. which new package is generating them and why aren't they ever deleted sans sysadmin intervention?
They are all zero-length file type 'p' - named pipes.

Gotcha! Kate is the culprit. Lsof shows lots of plumbing going on, so I started with a fresh reboot, launched the usual suspects one at a time watching /tmp. The 3 named pipes appeared only after I launched kate. Since I may open and close kate many times during the day, and kate does not clean up after itself, the defunct pipes accumulate with with three random letters as their suffix. I thank everyone who offered assistance in this matter.

I haven't come across that behavior from Kate but I don't use it a lot. Does

Code:

slackpkg search slackware64

show that you've installed everything?

I'm not convinced these named pipes come from Kate, although they do appear upon launch. I can't find any instance of QQueue or any other named pipes in the Kate git sources. This happens on only my Ryzen box, not an A6 laptop.

Thank you, RadicalDreamer!
I use rsync to mirror slackware64, then `upgradepkg --install-new`, so I'm not sure this is a missing dependency issue. I may have done the rsync during the mirror updates, so will try that again. Just a local mystery, nothing for the Kate developers to hassle over.

Have you enabled the GDB plugin?

Thank you for your help!

Issue isolated to something in ~/.local. Named pipes no longer appear with a blank .local. I'm interested to know which setting caused this, but I'm closing this as a personal mystery. I appreciate your helpful suggestions!

In Kate, Settings --> Configure Kate --> Plugins --> GDB. And you get them back.
