It should happen before disk access across the CI bus is even possible.

Unless youLre running an NI cluster. If PEDRIVER is loaded shutting the decnet circuit used by it must crash the node.

I would have thought that shutting off decnet will not affect SCS
traffic. If it happend that it did, AND there were two or more nodes
in the cluster trying to communicate and failing, I would expect one
or more nodes that lost quorum to hang for RECNXINTERVAL seconds
(by default, 20). After that, one or modes might bugcheck with a
CLUEXIT exception.

A SSRVEXCEPT exception much more likely indicates something is wrong
with the software.

If it helps in the discussion the crash happened very quickly.
