Druid连接池 can not open connection

[太阳王louis]

频繁对数据表进行删除和插入，几次就崩了，求指导

连接池设置：
##druid连接池
druid.filters:stat

druid.maxActive=10
druid.initialSize=1
druid.maxWait=60000
druid.minIdle=1

druid.timeBetweenEvictionRunsMillis=60000
druid.minEvictableIdleTimeMillis=300000

druid.validationQuery=SELECT 'x' FROM DUAL
druid.testWhileIdle=true
druid.testOnBorrow=false
druid.testOnReturn=false
druid.removeAbandoned=true
druid.removeAbandonedTimeout=120

错误信息（部分）：
com.alibaba.druid.pool.GetConnectionTimeoutException: wait millis 60040, active 10
at com.alibaba.druid.pool.DruidDataSource.getConnectionInternal(DruidDataSource.java:1124)
