This bug is fairly old but still exists in the 4.2RC versions, so I'm posting it here since it is quite severe:

Random IRQ_NOT_LESS_OR_EQUAL, BAD_POOL_HEADER & MEMORY_MANAGEMENT BSOD's occur on Win hosts when shutting down a VM or saving its state, while at least one other machine is running.

Tested on both XPsp3(32bit) and 7sp1(32bit) on two different computers with all 4.1 and 4.2 versions.

To reproduce: Start 2 VMS running only are bare live linux. Let one running, while saving the state / resume the other. Repeat. It might take upto 10 tries until host BSOD occurs.

My experience is identical to this as well for the filed bug, all along I thought it was a unique anomaly not reproducible by anyone.

The semi-random crash on 32-bit Windows hosts (and some others) should be now fixed and the tickets were updated.

THANK YOU! Special thanks to the devs for finding time to fix it in the middle of a major release. You guys are awesome
