Cluster crash when pod Re-join after been killed

ohad kelmanohad kelman EntrantCurrent User Role Beginner
Hello all,
We are using:
PXC galera stateful state
Ws-rep
PVC 100g x 3
with MySql on K8S
Using method Multi master for each pod

When I am killing a pod from the K8S UI, in order to test High availability, by the time that the POD restart to return to the cluster as the 3rd pod, it (guessing) hold corrupted data, and for some unknown reason Sync with the remain healthy PODS, his corrupted data, leaving the entire Cluster down.

Does any one knows why it is happening and have a solution for it ?
