GM(VINF_EM_DBG_HYPER_ASSERTION) Assertion at PGMAllPool.cpp:2476

Reported by: jdpickens Owned by:
Component: other Version: VirtualBox 4.1.16
Keywords: VGA Cc:
Guest type: Linux Host type: Windows


I'm getting this error with ever increasing frequency. There is no pattern as to when it occurs. The end of the VBox.log is always the same. If anyone has a workaround, I'd greatly appreciate it.

I just updated to the latest Ubuntu components and the error persists. So, I suspect the problem is indeed in VirtualBox -- not in Ubuntu.

comment:4 by jdpickens, 12 years ago

I've been using VirtualBox for over a year for 8+ hours a day. This problem used to occur once every 3 or 4 weeks. I dismissed it as some sort of glitch in my environment. But as I have updated to later versions, the crash has become more frequent. Since updating to 4.1.16, the crash happens 2 or 3 times a day.

Could you give me a hint as to what triggers the problem?

The error -1701 means that VirtualBox ran out of space on its hypervisor heap (which has a max size of 1.25MB in your case - see cbHyperHeap in the log file). This is the default setting for "usual" VMs, which means most people on this planet use it and don't have problems.

Can you try if lowering the memory size for this VM helps? Right now it has almost 3GB, can you live with 2GB for a while? It'll save a bit of hyper heap, possibly enough to make the problem go away. Once this is confirmed we can discuss the options, because so far it's not known if this really is just a case of "a tad too little heap".

No response, closing. If you have comments, please add them to #10745. Enabling VT-x in your BIOS should solve the issue as well.
