I just tried to reboot one of the boxes without kern.ipc.maxpipekva=104857600 to check for kva problems
but crashes persists, though the stack is completely different now. This time I included all the corrupt
parts of the stack that I had stripped in my original email but they are similar (from frame 18 to end).

Any ideas ?

Unread portion of the kernel message buffer:
