Description (partial)

HA failures are detected if HA core-to-core test is enabled. 
8 or 16 cores stop responding to show commands and stop processing NAT traffic
CGSE+ console (accessed using the command 'service-attach location <CGSE+ location> will be unresponsive

There is no specific condition. Apparently, it is a CPU level issue and happens when there is an interrupt between the 'branch likely instruction' and a 'delay slot'. Hence there is no apparent condition at the usage level
