Problem prevention measures:
- Connection pooling optimization: identifying applications that are not using connection pooling (via the

Long-term optimization:Based on historical connection count data (get_active_connections(log) adjustmentsmax_connectionsand connection pool size, it is recommended that 20% redundant capacity be reserved for unexpected traffic.
