Similar problem has been detected: Background story: "Maximum number of xclients" or some similar message came when trying to start vlc. This resource preassure is mainly triggered by running several docker instances with firefox running inside of them; closing several tabs/windows will eventyally get things "back to normal". As a workaround to closing tabs I switched to a virtual console, logged in as a different user, ran startx and played the video. After playing the video I pressed Alt-F1 to switch back to the original X session, and at that point there was some "blink" and this automatic crash report occurred. reporter: libreport-2.13.1 backtrace_rating: 4 cgroup: 0::/user.slice/user-5000.slice/session-8.scope cmdline: /usr/bin/kcminit mouse crash_function: qt_message_fatal executable: /usr/bin/kcminit journald_cursor: s=ee115a52bae946bdbce6154080f01d55;i=6dfbfbd;b=de0089d5fc844ec29168df94f550a410;m=4b640578567;t=5b21fa7cf6f39;x=b60f3a91ef65ce1 kernel: 5.7.15-200.fc32.x86_64 package: plasma-workspace-5.18.5-2.fc32 reason: kcminit killed by SIGABRT rootdir: / runlevel: N 5 type: CCpp uid: 5000 xsession_errors:

The system is otherwise usable (although at some point opening new tabs in firefox will result in failure as well).

This message is a reminder that Fedora 32 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 32 on 2021-05-25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '32'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 32 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
Fedora 32 changed to end-of-life (EOL) status on 2021-05-25. Fedora 32 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
