I have been using VBox for a long time without any major problems. Recenlty I reinstalled host operating system and installed fresh VBox, a new hybrid hard drive was installes (Swagate Momentus XT 750GB) . Unfortunately I have been experiencing many problems, with all virtual machines (Windows, Linux, OpenSuse, 32-bit, 64-bit). Virtual machines will either stop responding or will restart automatically. I have tries diferent stting for each virt. machine nothing helped. Laptop has 6GB RAM (about 4.5GB free), Intel i7 CPU.

Here's the latest crash

Attached in vbox log from th machine that sust crashed (Windows7 pro 32-bit).

Appreciate any help troubleshooting it.

The log you provided does not show any error, but seems to be incomplete. Make sure the VM is shut down before copying the log, and also make sure you post the log from the correct session.

And please don't use the forum for reporting bugs. See here: https://www.virtualbox.org/wiki/Community . Moderators, please do not hesitate to point that out whenever appropriate.

If you're not sure whether something is a bug, use the forum. If it's obviously a bug (and a crash such as this is), report a bug on the public bug tracker. Bugs reported only through the forum are unlikely to get much attention. It is also a lot more effort to get sufficient diagnostic information through the forum.
