tomcat自动停掉

// An highlighted block
#初始化连接数
jdbc.initialSize=5
#最小空闲连接数
jdbc.minidle = 80
#最大连接数
jdbc.maxactive = 100
#最大空闲连接数
jdbc.maxidle = 30
#获取连接最大等待时间
jdbc.maxwait = 20

jdbc.removeAbandonedTimeout=10
jdbc.removeAbandoned=true

还是没有用，大概两个小时就挂了，也没有什么特别的报错日志，只有一些销毁日志。
截取一个时间段的内存监控发现内存占用率一直在升高，知道tomcat自动停止，输出以下日志

不知道是不是内存泄露，如果是，是不是连接池配置导致的，找不到理由阿，还是Hibernate获取连接池的时候没有正确的获取,因为我发现我们的项目中有地方用到了openSession() ，和种获取连接的方式，虽然主动关闭了 ，但是就不归连接池管理了吧，哎 反正我是没辙了 时间太短 也没有报错信息，不知道大神们有何高见。
