VB 7.0.12 freezes randomly when copying or moving big files to VB shared folder

[dbuitel]

Hi

When I copy big amounts of data ( hundreds of Mb) from a folder inside Virtualbox to a VirtualBox shared folder, VirtualBox randomly freezes and after some time the VM reboots. After the VM has rebooted, I can copy or move the rest of the files. Sometimes it freezes again and reboots.
I checked the file systems for errors, both in the VM and the host system. No errors were found.
I have attached the log file from a session were the VM froze and rebooted.

Does anybody have an idea what the problem is and how it can be solved?

Thanks in advance, Dick.

Your Windows guest had a BSOD. If it created a minidump file in C:\Windows\Minidump, do the following:

In the Windows guest, install WinDbg Preview from the Microsoft Store, which is a (somewhat user friendly) modern version of the (in)famous WinDbg. Open the minidump file in WinDbg Preview, which will automatically execute !analyze -v and hopefully provide a good backtrace of the crash.

Thank you for the hint!

Analysing the minidump shows the following call stack:

Is this of any help?

The call stack confirms at least that the crash happened in VBoxSF.sys. Can you provide a zip file with the complete output of !analyze -v?

[dbuitel]

I executed the !analyze -v command in WinDbg and attached a zip with the output in .txt and .dml format.

Thanks for the debug outputs. From my POV, the following functions on the stack indicate in which area of code the crash happened:

Code: Select all

__RxCommonWrite()
__RxWriteReleaseResources() - VBoxSF+0x71332
__RxReleaseFcb() - VBoxSF+0x1717
ExReleaseResourceLite()

This is beyond my current knowledge. I'd suggest to create a ticket in the Bugtracker.

[dbuitel]

Thanks for your advice. I have created a bug report https://www.virtualbox.org/ticket/21937.

I updated to Virtualbox 7.0.14, but I encountered still the same issue.
