Failed assertion in virtualbox-ose 4.1.18

[Kamil Choudhury]

Went ahead and recompiled without DEBUG and DBUS (we are running headless, after all). 

Stable for two days. 

Of course, this begs the question of whether or not the assertion is correct or not...

Subject: Failed assertion in virtualbox-ose 4.1.18

Hi all:

I've got a troublesome Win2K8r2 guest on a Virtualbox/FreeBSD 8.3-RELEASE
AMD x6 host.

The guest is running headless, with two SATA discs, 2 cpus and 6 gigs of RAM.

Special consideration: I compiled virtualbox using the --disable-hardening compiler option.

My port options were:

[X] DBUS            D-Bus support
[X] DEBUG           Install debug symbols
[X] GUESTADDITIONS  Build with Guest Additions
[ ] NLS             Native Language Support via gettext
[ ] PULSEAUDIO      Support PulseAudio sound server
[ ] QT4             Build with QT4 Frontend
[X] UDPTUNNEL       Build with UDP tunnel support
[X] VDE             Build with VDE support
[X] VNC             Build with VNC support
[ ] WEBSERVICE      Build Webservice
[ ] X11             X11 support

The host starts up okay, runs for a period of ranging from half an hour to five hours,
and then invariably crashes with the following error in the log:

00:35:50.612 !!Assertion Failed!!
00:35:50.612 Expression: pTimer->enmClock == TMCLOCK_VIRTUAL_SYNC ? enmState ==
TMTIMERSTATE_ACTIVE : enmState == TMTIMERSTATE_PENDING_SCHEDULE || enmState ==
TMTIMERSTATE_PENDING_STOP_SCHEDULE

Googling doesn't seem to reveal a great deal, and I have not yet done a source dive to
figure out what's going on. It's especially perplexing given that there is another
Win2K8r2  VM running flawlessly on the same host (albeit with 1 CPU, 2 gigs of RAM and
1 SATA disc.)

Any assistance would be greatly appreciated. Has anyone ever seen anything like this?

Thanks,
Kamil
