Ever since I tried out the AI plugins (and later removed them again), my machine totally hangs during /admin/upgrade. Not every time but approximately 80% of the time. Usually my whole EC2 instance freezes and I have to do a hard reboot through the AWS EC2 web UI. Today it hangs again. To my surp…

@Jagster @uwe_keim please could you report the output of these commands cat /proc/sys/vm/overcommit_memory cat /sys/kernel/mm/transparent_hugepage/enabled On my systems I have # cat /proc/sys/vm/overcommit_memory 1 # cat /sys/kernel/mm/transparent_hugepage/enabled always madvise [never]

$ cat /proc/sys/vm/overcommit_memory 0 and $ cat /sys/kernel/mm/transparent_hugepage/enabled always [madvise] never

Thanks @uwe_keim - I’m going to suppose that those kernel tunables are the reason you needed to add swap, even though it didn’t seem to be used. (The same would apply if you’d needed to add loads of RAM, because the total available memory is RAM+swap.)

I can change server settings any time if you recommend to do so.

[Bild] Uwe Keim: change server settings any time if you recommend I do recommend! This will fix it for future reboots (note that it overwrites files without checking the current state): echo 'sys.kernel.mm.transparent_hugepage.enabled=never' > /etc/sysctl.d/10-huge-pages.conf echo 'vm.overc…

I’m trying but getting this: $ echo 'sys.kernel.mm.transparent_hugepage.enabled=never' > /etc/sysctl.d/10-huge-pages.conf -bash: /etc/sysctl.d/10-huge-pages.conf: Permission denied $ sudo echo 'sys.kernel.mm.transparent_hugepage.enabled=never' > /etc/sysctl.d/10-huge-pages.conf -bash: /etc/sysctl.d…

Try running it in a root shell, it might be struggling with being in a normal shell. (You’re sudoing the echo, but not the pipe to the file)

Indeed, several ways to do it, here’s one sudo sh -c "echo 'sys.kernel.mm.transparent_hugepage.enabled=never' > /etc/sysctl.d/10-huge-pages.conf"

I’ve ran the scripts and rebooted. Then: $ cat /proc/sys/vm/overcommit_memory 1 and $ cat /sys/kernel/mm/transparent_hugepage/enabled always [madvise] never (So first thing changed from 0 to 1 but second thing still returns the same).

Ganze Maschine hängt sich beim Upgrade auf.

Seltsam. Was erhalten Sie von

cat /etc/sysctl.d/10-huge-pages.conf

Versuchen Sie es vielleicht noch einmal mit dem Echo?
