I've been seeing a crash when closing VirtualBox.exe that is almost never reproducible. Few days ago I managed to get a crash dump and ran the analysis, see below. At the time of the crash, I was closing the virtual machine after it had been running for ~24 hours. Unfortunately, I can't find the log files
I'm using the following: VirtualBox 4.2.8 (Cross compiled with VS2010-SP1 on windows 7 64bit, Target Host = x86) Host Win7 32bit Guest Linux 2.6 32bit Build Type: Release Please let me know if you have any questions.
