最近使用 MeterSphere 做接口测试时，平台页面偶尔会提示 SQL error happened,please check logs 错误!

MeterSphere 日志

查看日志可以看到 Connection is not available,错误信息，拿不到连接原因！

解决方案：

进入 MeterSphere 安装目录

修改 metersphere.properties 文件，增加连接池配置

#  maximum-pool-size可以根据自己需求调大些
spring.datasource.hikari.maximum-pool-size=50 
spring.datasource.hikari.minimum-idle=10 
spring.datasource.hikari.idle-timeout=600000 

最后执行 msctl reload
