On a regular basis (approximately every half hour), my system locks itself up. During these freezes the hard drive spins wildly and both dual core processors run right at 100%. Gnome-System-Monitor does not register what is using the resources. These lock ups use so much of the system resources that I am unable to do anything until they stop. The mouse pointer barely moves and clicking anything doesn't enact until after the system calms down again. It usually takes about five minutes for the system to go through whatever it is doing and releases the hold it has on both the processors and the hard drive. However, sometimes it locks up so badly that I have to hard boot the machine in the middle of whatever it is doing. With the hard drive maxed out, this is obviously quite dangerous.

I simply CANNOT have this happening. To say getting locked out of my system could be catastrophic is a huge understatement. Last night my system was in screensaver (xscreensaver - blank screen) and the hard drive was running maxed out. I could not get into the system and had to hard boot at 10:35. This happens way too often.

The logs show very little unfortunately. I will post system information below along with the logs from last night before it was hard booted. I use XFCE as a desktop environment to minimize system load.

Please help. I need to have this system stable and operational at all times. Have been using Fedora since Core 1. Only the later versions have been doing this. I upgraded from FC25 hoping it would help, but it has not.

nothing you provides spreads some light on your problem. One thing: Fedora 27 had have it's EOL . Upgrade to F28 and we may be able to help.

What may help to analyse it: CTRL+ALT+F3 => login as root , run "top -c" , CTRL+ALT+F1 back to your desktop and wait untill it happens. CTRL+ALT+F3 back into your Textwindow of top and check it out.

May I suggest a cold shutdown, then remove and reinsert the memory modules and the CPUs? What's the peak temp on them?

Okay, after stopping TOR and deleting Gnomesoftware and packagekit the lockups have been less. However, they persist. Still having issue with SSSD_KCM, as the following log shows. Any ideas?

System locked up today at about 17:25. Results from journalctl -xef from just before to just after incident:

Okay, system completely locked a short while ago. Contents from journalctl -xef (note- most of this was in red font, so it was BAD) and of course, when I went to see what process 16831 had closed so I do not know what it was:

From the sssd-kcm man page: SSSD Kerberos Cache Manager "In a setup where Kerberos caches are managed by KCM, the Kerberos library (typically used through an application, like, e.g. kinit, is a “"KCM client"” and the KCM daemon is being referred to as a “"KCM server"”. The client and server communicate over a UNIX socket."

kdeinit used to hog CPU time. While it does not specifically show up in Gnome System Monitor, I believe it may still be an issue. How do I keep it from over using CPU resources?

I believe this means rdtcustomercare was right. To me, it seems Firefox and rsyslogd get into an IO fight and lock up the system, though, I am certainly no expert at this or I wouldn't be having these problems. Is this the case? If so, how do I fix it, short of turning my computer into an artificial reef?

m.drahcir ( 2019-04-01 09:46:56 -0600 )edit

Trying the IONICE command to see if it helps by putting a leash on Firefox's IO scheduling. Will let you know if it works.

ionice -p 2 none: prio 4 [nooneinparticular@localhost ~]$ ionice -c3 -p 2382 [nooneinparticular@localhost ~]$ ionice -c3 -p 2555 [nooneinparticular@localhost ~]$ ionice -c3 -p 2081 [nooneinparticular@localhost ~]$ ionice -c3 -p 2079

ohhh yes... we are near it \o/ .. abrt-dump-journal-xorg and firefox .. that means, firefox is crashing in a deadloop and abrt-dump-journal-xorg is writing the crash messages to the disk.

all you now need to do is simple: stop abrtd and look inside the journal, what actually happend to FireFox. There is also a /var/spool/abrt directory, you may find infos there too.

Than we see, how we can fix this.

As a quick fix, to stop io wasted in case auditmessages are involved too, execute as root "auditctl -e 0" it temp disables the audit daemon.

rdtcustomercare ( 2019-04-01 16:21:35 -0600 )edit

BTW: why are you using pacman with fedora ?

rdtcustomercare ( 2019-04-01 16:23:06 -0600 )edit

Thank You rdtcustomercare. Okay, I auditctl -e 0 ed. When trying to view the journal, I get: "Failed to obtain all required information from journald". Going to /varspool/abrt gives me an empty coredump file and nothing useful.

I have no idea where pacman came from. I do not recall installing it, though Amazon did deliver the lemur a shipment of pomegranates which I did not order...

Latest update - today at Five PM, I could hear my hard drive maxed out, spinning uncontrollably. I tried to log in, out of xscreensaver, blank screen (uses very little system resources). The login prompt never appeared. The system continued to be maxed out FOR THE NEXT HOUR! At Six PM, I had to hard boot the system. This is completely out of control and should never happen. There are times I need immediate access to the information on this system and cannot have this happening. Several times during this hour I tried to CTRL+ALT+F3, but nothing. It never came up. Just blank screen, hard drive out of control.

I love Fedora. Have been with it since Core 1. I do not want to have to switch operating systems, but this is unacceptable. Please, suggest something. If I cannot get this fixed, I am going to have to ditch Fedora.

Please forgive the delay. I have tried several times to CTRL+ALT+F3 and log in as root. Problem is, the system will not let anything happen when it locks up. By the time I can finally log in as root, there is nothing out of the ordinary. System lock up happened while I was typing this - GKRELLM froze the clock (11:04 14 for the last six minutes), CPU and hard drive monitors maxed - the hard drive was run at anywhere from 40 - 75 MB per second (mostly read, only some write) when this happens.

Back to CTRL+ALT+F3 - last time I was able to do it, it showed: 10:32:12 up 1 day. 11:57, 1 user, load average: 0.58, 2.62, 2.04 Tasks: 233 total, 2 running, 175 sleeping, 0 stopped, 0 zombie, Mem: 4032940 total, 282352 free, 3334396 used, 416192 buff/cache, swap: 4177916 total, 2128120 free, 2049796 used, 779396 avail Mem

Typically, I have the following things open/running in the system: Firefox, latest edition (anywhere from 3 to 15 tabs open) - mostly text based websites without animation or scripts running; Evolution; GKRELLM; Gnome System Monitor; a terminal window; several LibreOffice documents; Telegram - a chat program (note: this has been going on long before the install of Telegram); one to three windows of Eye of Gnome (picture viewer) and on a semi regular basis these items may be open: Tor and xmms.

System froze again here, while writing this. Only locked up for four minutes this time. Fortunately, I have not had to hard boot it in a bit.

Obviously, having the computer inaccessible for large portions of time while I need to be using it is not acceptable. To me, it seems as if the system is writing a log of everything that has happened since the last time it went through the process, but I have no proof of that. Is this possible? If so, can I turn it off so the computer can be used without interruption?

Your systems shows all signs of an IO problem due to OOM or extensive io usage. As your swap is active, an oom is possible. IO problems can also be caused, if a million small files are written to the drive. Best Example is the "Runes of Magic" update process, which lags out a SSD drive and leads the same problems, you descripe.

Solution: We need to identify it with IOTOP . iotop can be run inside a cronjob and it can write to a logfile. Set one up pls. Make it "iotop --options >logfile;sleep 10;iotop --options >logfile;sleep 10;iotop --options >logfile;sleep 10; aso." or make a small bash.sh

Thank you rdtcustomercare. I will work on IOTOP first few free moments I have. Will have to research it as I have never used it before. As soon as I know something, I will post here. I really appreciate the suggestion and everyone's help.

Thank you. Will do the CTRL+ALT+F3 when I have a few minutes to go through the information it returns and post here. I do plan to upgrade as quickly as possible. Work has been non-stop and an upgrade usually takes me a week or so to get everything back the way I need it.

Also, thank you- I have actually pulled all memory, wiped down contacts with CRC226 and reinstalled. Pulled processors, cleaned them up, new Arctic Silver and back in they went... about a month ago. Right now Core 0 is running at 105.8F and Core 1 is 93.2F. When the processors peg out they can get up to high 120s, but rarely over 130.
