I have an Ubuntu 16.04 droplet on DigitalOcean and I'm trying to set up remote desktop capabilities for it. I followed these instructions through Step 2. However, when I start the VNC server using the vncserver command, it goes haywire and bogs down the server until it crashes. Here are excerpts from the log file:

This is the beginning of the log and it descends into more chaos from here with many different "Cannot fork" warnings. Nothing from the command line indicates that something is going wrong when starting the VNC server. Anyone have any ideas on what's going wrong here?
You are probably running out of file descriptors for the user running that process.
Check what is the current limit with ulimit -n and change accordingly.

I am getting this error. Though Agent seems to be running I have checked running state by calling
EXEC xp_servicecontrol 'querystate', 'SQLSERVERAGENT'
And it shows "Stopped." Then I call
EXEC xp_servicecontrol N'START',N'SQLServerAGENT';
And it shows "Running." After that I try executing the job by calling
EXEC dbo.sp_start_job N'SendCollectionSummaryReport' ;
And I get the Error: SQLServerAgent is not currently running so it cannot be notified of this action.
Then I called again EXEC xp_servicecontrol 'querystate', 'SQLSERVERAGENT'
And it shows "Stopped."
I realized that something is causing failure to start SQLServerAgent. Environment details below:

I have played with different versions of windows 10 inside qemu/kvm (proxmox) and all of them works fine except: "Microsoft Windows 10 Enterprise 2016 LTSB 10.0.14393 Version 1607".
I don't think that the problem is connected with proxmox itself. As I know proxmox is stable and reliable system that use qemu/kvm under the hood. So lets think more about qemu/kvm. However my proxmox versions below.

In any case I have not found any similar thread on proxmox forum. That's why I post my problem here.
This is clean original msdn iso from microsoft with confirmed hash sums(installed more then 10 times).
Steps to reproduce:
Create VM with next configuration
root#home:~# cat /etc/pve/qemu-server/102.conf
bios: ovmf
boot: dcn
bootdisk: scsi0
cores: 8
cpu: host
efidisk0: local-lvm:vm-102-disk-0,size=4M
ide2: iso-backs:iso/MS DaRT 10 Eng x86 x64.iso,media=cdrom,size=600320K
machine: q35
memory: 8192
name: win10-test
net0: virtio=C2:25:D9:DD:F2:4F,bridge=vmbr0
numa: 1
ostype: win10
scsi0: local-lvm:vm-102-disk-1,size=100G
scsi1: external:vm-102-disk-0,size=100G
scsihw: virtio-scsi-pci

usb1: host=09da:9090
vmgenid: 40cd47b6-35c4-47ab-8f9e-ed2acb618fcc
Install latest virtio drivers (scsi, netkvm, baloon, qemu-fwcfg)
Accept disk auto-partitioning (4 partitions will be created for this iso)
Wait installations end and reboot the system
Boot will stuck at proxmox logo
However, I can always boot from live cd (MS DaRT), to do that I need to manually choose harddisk from "Use a device" menu.
Once it load successfully there is a chance it will boot again an indefinite number of times. I can't figure out the reason of such behavior.
I have tried to avoid this problem by installing grub. But nothing has changed - I am still able to load system through live cd and always have a random chance to stuck at default load process.

I just downloaded SOAPUI 4.0.1 and tried to run it in Ubuntu 11.10. I run the file soapui.sh. The application started up and the window actually appeared, but then after a few seconds it closed. Looking at the terminal I saw that the JVM crashed. Below are the details of the error:
(process:4183): GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.30.0/./gobject/gtype.c:2708: You forgot to call g_type_init()

(process:4183): GLib-GObject-CRITICAL **: g_object_ref: assertion `G_IS_OBJECT (object)' failed
Problematic frame:
C [libgconf-2.so.4+0x15b99] gconf_enum_to_string+0xd59
Can anyone help? Thanks.
Look here: http://www.eviware.com/forum/viewtopic.php?f=13&t=7736
Look in ..../soapui-4.0.1/bin/soapui.sh:
#uncomment to disable browser component
#JAVA_OPTS="$JAVA_OPTS -Dsoapui.jxbrowser.disable=true" <- uncomment this line
if you are usising soapui.sh to start soapUI. If you used installer and using launcher than
in soapUI-*.vmoptions add -Dsoapui.jxbrowser.disable=true
that should do the trick.
I also have the same issue

This jxbrowser...jar is working with xulrunner-2.8...jar and native code doesn't full compatible with your OS dependencies.
jxbrowser it's used for 'HTML rendering' but works also without it.

It works also in FC16
