VM crash - Assertion Failed on 4.1.10 and 4.0.16

Postby zdinu » 31. Mar 2012, 09:41

Hello,

We got stability issues with both 4.1.10 and 4.0.16 versions running Windows 64 bit guest VM on a OpenIndiana oi_151a base OS.

Here is the kernel dmesg output:

It happens very frequently. We are running a mix of Linux 64 bit and Windows 64 bit VMs. It seems that only Windows VMs are in question. Here is a part of VM.log section:

08:18:25.550 !!R0-Assertion Failed!!
08:18:25.550 Expression: <NULL>

Please let me know what VirtualBox version is the most stable on Solaris hosts. I'm not sure I found one yet.

Thank you!

This guru seems familiar but I'll have to check if it's already been addressed. Guru meditations are mostly VMM internal errors that are usually host independent, so Solaris hosts is probably not the problem here at all. It might manifest more on certain hosts due to timing etc., but I digress, could you please upload the full VBox.log?

Hello,

I have attached the log file. In the meantime I have disabled largepages and ran increased the HyperHeap with:

VBoxManage setextradata <VMNAME> "VBoxInternal/MM/cbHyperHeap" "3145728"

Refferences:
https://forums.virtualbox.org/viewtopic ... 11&t=46974
https://www.virtualbox.org/ticket/8631

I will let you know if the crash occurs again after these changes made but please try find what's going on.

I really appreciate if we can fix the stability issue !

Thank you,
Dinu

This shouldn't be related to large pages, so you shouldn't need to disable them. Could you please try with large pages enabled with just the increased hyper heap size?

Hi,

Yes, I can enable the large pages again. It has been stable so far with the heap increased, or at least it didn't had a chance to crash.

I will keep you posted.

Thank you !
