VBoxSVC crashes randomly on Solaris host

Reported by: sunflower Owned by:
Priority: major Component: other
Version: VirtualBox 4.1.18 Keywords: VBoxSVC
Cc: Guest type: Windows
Host type: Solaris

Description (last modified by ramshankar) (diff)

At random intervals (sometimes a few hours, sometimes days) VBoxSVC crashes, causing all VMS running on the host to PowerOff. We are running Windows 7 and Windows XP guests on the same server. Definition for all VM's is identical. On average 25 VM's running on host, with plenty of resources available. All VM's show exactly same error in the logs.

Core dump of the VBoxSVC process would be useful along with the VBoxSVC log (check ~/.VirtualBox/VBoxSVC.log*)

How to enable core dumps can be found here: https://www.virtualbox.org/wiki/Core_dump

I attempted to upload a compressed core file, but I was limited by file size of the attachment facility. The core file is 6.6mb compressed. I have put it on our web site, you can download from here,  http://www.sa-pages.net/media/core.zip

The VBoxSVC.log is difficult to get as the VM's immediately startup again once they have crashed overwriting the log files already there. I will see what I can do.

Thanks for the core, will download it in a while.

Replying to sunflower:

The VBoxSVC.log is difficult to get as the VM's immediately startup again once they have crashed overwriting the log files already there. I will see what I can do.

The logs are rotated, the previous logs should be available with a ".x" appended to it's name, eg. VBoxSVC.log (current one), VBoxSVC.log.1 (previous), VBoxSVC.log.2 and so on. So you could provide the VBoxSVC.log.1 if it is the corresponding log when this crash happens.

I am aware of this, but for some reason when the fail happens, the broker immediately attempts to startup the VM's and I get 5 or 6 files that all have same contents which is the startup entries of the VBoxSVC. Example below. I am going to try and modify the broker to not startup VM's immediately, so I can preserve the logs.

Is there a restriction in VBox 4.1.18, as I have just noticed that I am unable to launch more than 24 VM's per host ? I have increased the default (sem-ids) semaphore count to 512, as we will need to run about 30-35 VM's per host but the problem still persists, I don't get semaphore errors. Unfortunately, I have had to rollback to 4.0.16, as the customer cannot have these crashes interfering in there production environment. I will have to setup a test environment in the next few days, to continue testing.
