VBoxSvc crash

[Jakob Østergaard Hegelund]

During a normal working day, suddenly all our VMs appeared to spontaneously restart. It turned out that VBoxSvc had crashed and that all the VBoxHeadless processes had therefore powered off.

VBoxSvc left behind a core dump. A 'pstack core' reports this interesting trace:

All other threads are in lwp_park() so I assume they are not terribly interesting.

Attached is a log file from one of the VBoxHeadless processes where this happened - the log only shows that VBoxSvc appeared to disappear.

Also attached is the core file from VBoxSvc.

Log file from VBoxHeadless that sees VBoxSvc disappear

... I cannot add the core file - even a bzip2'ed core file is 7.3 MB and trac only allows 4MB...

Please contact me directly for a download link to the core file.

Does this happen with VBox 4.0.10 too? And is it reproducible?

The core would be interesting if you have it. Either use a service like yousendit.com to upload or upload to ​ftp://ftp.virtualbox.org/incoming (write only access; others won't be able to see your file).

Replying to ramshankar:

I have not yet upgraded to 4.0.10 (but will shortly).

The error has not happened since.

The core would be interesting if you have it. Either use a service like yousendit.com to upload or upload to ​ftp://ftp.virtualbox.org/incoming (write only access; others won't be able to see your file).

I previously uploaded the core to the FTP site as core-9049, on request from Frank Mehnert from Oracle.

If the file has gone missing, let me know and I will upload it again.

Please reopen if still relevant with VBox 4.1.4.
