We have below setup:
3 Node Percona XtraDB (Galera Libraries Installed)
Server version: 8.0.21-12.1 Percona XtraDB Cluster (GPL), Release rel12, Revision 4d973e2, WSREP version 26.4.3
We are seeing below wait event resulting on replication getting paused and max_connections and max_user_connections reaching max limit.
wsrep: replicating and certifying write set(-1)
Any advise on tuning and resolving the issue.
