druid版本 1.1.22 参数: {"initialSize":70,"minIdle":70,"maxActive":80,"maxWait":1500,"removeAbandoned":false,"removeAbandonedTimeoutMillis":180000,"timeBetweenEvictionRunsMillis":15000,"minEvictableIdleTimeMillis":54000,"maxEvictableIdleTimeMillis":54000,"validationQuery":"SELECT 'x'","testWhileIdle":true,"testOnBorrow":false,"testOnReturn":false,"keepAlive":true,"useUnfairLock":true,"filters":"stat"}
问题:线上突然有部分机器activeCount持续缓慢增长,直到达到maxActive,服务不可用
dump内存发现 activeCount=65,但是此时应用上没有使用连接的线程
