I am new to Percona XtraDB Cluster and exploring. Couple of days before faced an issue with the cluster which brought down entire cluster. I did go though the logs and suspect the issue was caused by connection issue of nodes to peers. The cluster contains 3 nodes and application talks with the database via Haproxy. Need some expert advice if it was a connection issue or something else that I am missing. I rebuilt the cluster as this was our QA server by bootstrapping one node. Need to know if this is caused by a configuration issue or not so that similar scenario does not happen on production servers.
I am attaching the logs from all the nodes.
