Guru meditation when taking snapshot (PGM_PAGE_GET_STATE(pPage) == PGM_PAGE_STATE_ALLOCATED) => Fixed in 4.0.4

[diagiman]

Virtualbox crashed when taking snapshot and showed guru meditation exception

[diagiman]

Now VM crashes every time I take snapshot from running machine
But if I pause it before, and remove pause after that - everything goes ok

[diagiman]

It seams to be caused by #7966 (after memory leak). Now that is fixed and ticket can be closed.

Thanks for the feedback!

It just happened with 4.0.3 r69765. So there is something else causing it, not only #7966. Pausing VM before taking snapshot workarounds bug (even after #7966 caused leak).

I believe that I have encountered the same problem.

I have posted a complete VBox.log that demonstrates the same problem on PasteBin  http://pastebin.com/SBjA6pfr (the log file is too large for me to upload here.) N.B. This is a second log file - the log file that I quoted from above has already been overwritten.

In case it's relevant, here is cygwin's /proc/cpuinfo output from the host machine:

Don't worry - VirtualBox is not being run through Cygwin in any way.

This will be fixed in the upcoming maintenance release.
