To clarify, you upgraded to rc6 and hot-attach worked fine without any XML changes?

@ren88 Any luck with that XML change?

Try this: Stop the VM, Edit the VM, toggle from 'Form View' to 'XML View' near the top-right. Look for the following XML: <controller type='usb' index='0' model='qemu-xhci'> And add in the ports='15' attribute, like so: <controller type='usb' index='0' model='qemu-xhci' ports='15'> Your model may be 'nec-xhci' or 'qemu-xhci', but adding the ports attribute is all that matters. Save that, Start the VM and try to hot-attach a usb.

@ren88 Does your VM that you're trying to hot-attach a USB device to use a USB2 controller or one of the USB3 controllers?

"configured as JBOD and not any RAID mode" would be in your motherboard's BIOS.

Thanks for testing. I suspect you can boot back in to normal mode and start using VMs and Docker apps again since it seems to just be a issue related to Safari (most of the machines I was using to test Nginx memory usage had active VMs and Docker apps running). I can also confirm Chrome works fine too -- no memory increases throughout a parity-check with Chrome. Now on to see what's special about Safari...

I think I can reproduce after a while with Safari (i'm also on macOS 10.12.6). Once I completely close Safari, from the Dock, the memory seems to free up... meanwhile Firefox still has the Dashboard page open in a tab. I'm messing around with 'nchan_stub_status' to see what's happening and it looks like the Stored Messages stays at 3 for a while but then begins to increase after 30-40min but only when Safari is connected it seems. I'm trying with Chrome now to see if it exhibits the same behavior as Safari. When you get a change, and are able, could you give Firefox a shot? You might first need to close the unRAID tabs in Safari, then fully close Safari to get a clean state. I see two issues for nchan possibly related but I'd like to determine which conditions (Safari?) are causing this first before chiming in there: https://github.com/slact/nchan/issues/413 https://github.com/slact/nchan/issues/445

@John_M When you run your parity-checks, do you leave the browser open on the Main page the whole time? If so, which browser and version are you using? I have four 6.5.0 (or newer) machines here running a parity-check and trying to reproduce the issue you're seeing. About 20min in so far and htop isn't showing any nginx memory growth yet. I have Firefox browser tabs open to each of the servers.

For some reason php-fpm isn't running. Try running this command to manually start it up: /etc/rc.d/rc.php-fpm start

After you remove the topology, save, then go back to add in topology, what does that cpu/topology block of XML that you typed in look like?

Just wondering which version of unRAID did you upgrade from?

Besides the folder rename (EFI- to EFI) you may have to tell your BIOS to prefer booting the flash via EFI. I guess it can't hurt to try seeing if EFI boot helps.

@Hoopster Are you booting via EFI? If so, try changing your BIOS to boot legacy (non-efi) to see if that makes a difference.

The accelerated Vega iGPU drivers are in Linux 4.15 which would be needed for Plex transcoding presumably. We only include the Intel iGPU drivers at this time but we're open to including Vega iGPU drivers when we upgrade kernels, Plex supports it and the Vega iGPU drivers don't conflict with normal dedicated AMD video cards that would normally be used for passthrough.

This issue should be fixed now.

@Hoopster @Strega try this to get non-gui mode working: Power off the server, pull out the usb flash drive and plug it in another computer. Edit the syslinux/syslinux.cfg file on the flash drive. Look for the following in the file: ... label unRAID OS menu default kernel /bzimage append initrd=/bzroot ... And add ' nomodeset ' between the append and initrd strings, like so: ... label unRAID OS menu default kernel /bzimage append nomodeset initrd=/bzroot ... Save. eject the flash and try it in the server again. @Hoopster I think you fixed one of your servers like this before but just want to be sure.

That "strings-BSD" binary comes from the 'util-linux' stock package with unRAID. Looks Slackware updated the util-linux package on 9/26/17 so it was included in one of the 6.4.0-RCs:

Looks like that 'strings' binary comes from the 'binutils' package. DevPack (nerdtools' cousin plugin) has that package available to install.

Updated Sync to version 2.5.12

It cancels out the running command if closed. You could use 'screen' or 'tmux' to have the session persist though.

unRAID 6.4.0-rc10b might cause idle Ryzen cpus to randomly freeze again, see this post for the reason and possible workaround:

MSI did end up releasing a BIOS update that allows one to enable SVM (sorry, I must have posted on another forum about this). I moved my development VM on to this Threadripper machine (no GPU passthrough) and performance is great.

Plex container has been updated to version 1.9.2.4285 now

Could you go in to your BIOS and enable 'Above 4G decoding' to see if that makes a difference?

@l0crian@mixellburk Thanks! The new beta bios does in fact allow SVM. I'm back in business! Now, on to some real testing....
