I am now getting a similar Issue , even after stopping all VM's , removing apps , full AV and Malware scans ( some removed ) , changing passwords . I am still getting giving a 20%-60% CPU thread to Kernel_Processes .

Literally the system is running idle with everything else and I have a constant spiking 20-60% thread going to Kernel_Processes

I opened a ticket with QNAP where I removed the known malware found in their FEB/MAR 2019 firmware . However the CPU is still spiking with this thread , even with everything disabled . My ports are still open , so will try closing or changing them next

I don't think @90Ninety is saying QNAP distributed malware-infected QTS versions.

I think they meant they were running one of those firmware versions and, at some point, discovered malware running on it (thus, their firmware wasn't immune to infection). ;)

You may really want to enable SSH access to your NAS and use the "top" command to identify the running process. 'Kernel_Processes' may be a random python process and knowing more about it wouldn't hurt. If you ever identify the PID of th process 'cat /proc/PID/cmdline" may help.

Any luck with this? I've been troubleshooting my QNAP 453mini for a while now (well, since we became aware of the Malware infection). System processes continue to average 60-70%, mostly due to manaRequest.cgi, disk_manage.cgi, and appRequest.cgi. If I run anything minimally demanding the GUI becomes unresponsive. QNAP took a look at it but they don't seem to know what the problem is. I wonder if you guys had better luck. The path to factory reset is getting closer by the day.

if you think you have a malware infection, a complete reset should be done asap

Were you able to solve? If so, how did you manage to do it?

I've been having the exact same issue with the exact same processes and still can't figure out the cause.

I believe this only started with the QTS version that introduced the QuMagic apps.

Thanks

I also noticed an increased load on my TS-453A in the last few weeks(/months?). The web itnerface is responding very slowly. Using a SSH connection with the top command it is clear that the load goes up all the time when the web interface is up. What are all those "system processes" in resource monitor?

I am in the same boat. I was at 100% CPU all the time on a 451+. Worked with tech support to quit virtually every process. Now CPU sometimes drops to 40% but currently at 99%. Please fix, Qnap.

so what process is using your cpu then ?

asking qnap to do something here will do absolutely nothing

Thanks. The reason qnap support could not really fix it is that the guilty processes constantly hop around. Sometimes Qmail is at 50%L-75%. Then it drops and manarequest.cgi, or msgexport.sh or diskmanage.cgi or chartreq.cgi or hal_daemon or daemon.mgr jump up. Support said that Qmail should not be the problem, but could not locate the issue otherwise.

This is going for quite some time. I Have 2 Qnap devices TS251 and TS472.
Different firmware etc does not really matter.

The thing to watch is mariadb. alias mysqld this is for always the culprit.


What always helps for me is to restart mariadb.

ssh into the NAS and " /etc/init.d/mariadb.sh restart "
This 95% of times fixes high CPU load. Still not sure why it happens sure I use a lot of stuff. vm's, containers, snapshots etc etc.

For sure I know Plex was one of the apps causing it for quite some times I am not using that anymore. Still I have this problem one a while.
My suspect is in backup stuff but not sure off that neither do I have evidence of this at the moment.

Never the less it is annoying this problems is there for a long time allready and should be addressed by Qnap.

Had the same issue. Noticed on the dashboard I had an background indexing task running. When I stopped that, the CPU reduced and the mysqld process went down to a normal level.

I am in the same boat. Same issues. Same culprits in Resource Monitor. I have worked with support for months, shutting down tons of processes, reducing a lot of functionality, making Qmail check as infrequently as possible, pausing all indexing, etc. But my CPU is still near 100% most of the time.

Qnap can't fix it. I'm starting to think this 451+ is a lemon.
