Node auto failover | 7.6.0 2076

The following bug was found during Capella testing.
ami - 
couchbase-cloud-server-7.6.0-2076-x86_64-v1.0.28
CSP - AWS
all search node had ~99% cpu utilization for 3.5 hours.
The node auto-failover did not occur in this window but as soon as there was an OOM kill, the node was auto failed over(service restart,etc?)

From the ui it can be seen that there was no RAM contention in any of the fts nodes and high cpu utilisation was always at ~99% so there's a blackbox for the reason of node failover, i.e. is it because of cpu contention or oom kill that's causing the failover.
{{}}

the node got successfully added into the cluster again after about 6 hours.

the node to faillover was - svc-s-node-010.zumnyloovvbb6uxi.sandbox.nonprod-project-avengers.com
