排查过程

  1. 排查日志后发现数据库连接打满 !Pasted image 20250724094105.png

  2. 查看hertzbeat数据库监控显示从4点开始出现连接未释放状态，直到6点到7点之间超过最大500连接限制 !Pasted image 20250724094256.png

  3. 查看日志从4点半开始出现socket超时，但不是数据库类型的异常 !Pasted image 20250724094428.png

  4. 查看hertzbeat 应用监控发现从4点起线程并未出现递增或者较大波动情况 !Pasted image 20250724095212.png

  5. 说明不是socket或者线程导致的问题，继续往下查看日志 车牌识别未执行的情况下，线程池出现了频繁申请连接的情况
