Anything that can crash ESX is an ESX bug.

Subject: Superpages and VMware ESXi 3.5u4 crashes

Hello,

FreeBSD 8.0-RC1 on VMware ESXi 3.5u4, under moderate load (I was 
building mysql51-server & apache20 at the same time) the VMware ESXI 
_host_ system will crash with superpages enabled in a FreeBSD guest. 
Reproducible.

If I disable superpages with vm.pmap.pg_ps_enabled option FreeBSD guest 
will not be able to crash the host system.

Trying to figure out of this bug in VMware or a problem with my 
hardware. Host machine was up for 30 days without crashing prior to 
trying out 8.0.

Has anyone else had problems with superpages implementation in FreeBSD 
crashing VMware ESXi 3.5? Seems like a bug in VMware and I'd like to 
report ..

-Peter
