一、日志报错
11月21号下午4点20左右查看43.148的weblogic 日志报如下错误， 16:20 weblogic报如下错误，16：20-17:05一直报，无其他报错。####<2023-11-21 下午04 时20 分27 秒 CST> <Info> <Common> <bssapp5> <ctcrmServer> <[ACTIVE] ExecuteThread: '102' for queue: 'weblogic.kernel.Default (self-tuning)'> <<anonymous>> <> <> <1385022027125> <BEA-000627> <Reached maximum capacity of pool "JDBC Data Source-ctcrm", making "0" new resource instances instead of "1".>
在查看连接业务数据库时当时有大量的43.148发过来的连接，
如下：

二、原因分析
从上边的中间件报错和crm连接情况初步分析如下：
由于应用大量的请求连接，导致中间的连接池资源被占满，其他应用在请求时，无法申请资源导致weblogic报Reached maximum capacity of pool "JDBC Data Source-ctcrm"错误。
三、处理办法：
1. 尽量释放不活动的会话。（修改weblogic参数非活动连接超时:）
2. 会话完成尽快colse。
