VM is causing Guest OS applications ( Slack/Intelli J ) hung

[Sandeep Reddy]

I have windows machine with 32 Gigs RAM and core i7 with 8th Gen. I have installed Ubuntu inside my Oracle VM with 2 cores(Out of 8 Cores) and 8 Gigs RAM (Out of 32 Gigs RAM).

Guest OS application slack or IntelliJ works fine without any issues until I start the Ubuntu using Oracle VM 6.1

As soon I start my Ubuntu on my VM, slack and IntelliJ freezes for every 10 minutes and I need to wait for 2 to 3 minutes to respond and do my work, it became a routine for every 15 minutes.

Unfortunately I do not have any logs because I do not see any network/cpu/disk usage spike, when these applications get hung.

Hello,

I am facing a similar issue on a similar configuration:

• Host with windows 10 64 bits - 16GB of RAM - core i7
• Guest with Debian 9 - 3 cores - 8 GB of RAM

Not 100% sure, but I think that issue first appeared after installing Virtualbox 6.1.14.

What happens is when the VM is running, after a while (hard to define how long but let's say after 1 hour) my Slack windows desktop application starts freezing.

Once frozen, killing the Slack task and relaunching it does not help = slack displays a black screen. Sometimes Slack gets back functional after 2 to 3 minutes, sometimes it never does.

I recently noticed that Slack went systematically back functional after exiting the guest VM.

I also noticed yesterday that if I disable the screensaver inside the guest VM, the problem nearly disappears: Slack almost never gets frozen, and when it does it is stuck for a couple a seconds only.

Wanted to share this as a workaround for people facing a similar behavior

Hi jmval,

The workaround with disabling screensaver inside the guest VM helped me lot. Thanks!

I also saw the description of a similar issue on reddit: ​https://www.reddit.com/r/Slack/comments/gfcfse/slack_repeatedly_crashing_due_to_conflict_with/

On my machine the app hang report (the one Windows host generates) indeed contains the following:

I'm having the same issue.

Host = Core-i7, 32GB, Windows 10 Pro. VirtualBox 6.1.22. (But this has been a problem with earlier versions.)

Running a CentOS Linux Guest (configured with just 1 vCPU, 3GB RAM, NAT Network) appears to cause Slack to occasionally become unresponsive, in the way the OP described. If I kill the guest (but leave VirtualBox running), then Slack recovers and runs fine.
