References to vmhba1 and SCSI Adapter - I would run a diagnostic on whatever type of controller card that is, as a start point.
Check storage adn network firmwares with vmware compatibility matrix.
Probavly one of them is a root cause of your problem.
I checked my ESXi Version with the installed firmware of the server.
There were some incompatabilities between BIOS version/ DELL PERC controller and my installed VMware ESXi Version.
I now updated all my firmware to the latest as well as the ESXi Version to fit the compatabilities mentoined in the VMware Compatability Guide.
Since i did that there were no crashes again.
