I need to be able to find the problem. Any assistance ?

SSH (Putty) into the host.

Go to /var/core. There you can find dump files named vmkernel-zdump.x.

The first part in this file is readable, the bigger part at the end not.

Search for the stack dump of the PSOD there.

For example search for BlueScreen.

Post the backtrace here.

Or you have a screenshot from the purple screen. It is the same.
