在oracle hotspot上运行tomcat 7.0.32 jdk 1.7.0_7我得到了这个奇特的输出。
我希望能够确定内存泄漏,因此我运行了jstat -gc -t 2000
。起初一切看起来都合理。我每隔2秒获得一条新线。但在某些时候,时间戳列开始变得怪异。它在1秒后返回,然后在5秒后返回,然后是2,然后是7,直到它达到时间戳518058.9,最后它说出" Screwit。你有足够的数据儿子。去做吧。 Imma称之为一天。"
Werid?为什么会这样?我被迫重启了这个实例。
可能存在数据库错误并且c3p0 哭了DEADLOCK,但这不应该停止jvm报告gc利用率?对?实际上 - 不要停止报告,只是停止增加时间戳。
jstat输出:
