问题描述
tomcat总是运行一段几天之后死机，GC日志如下：Application time: 10.9037210 secondsTotal time for which application threads were stopped: 0.0019070 secondsApplication time: 63.4705310 seconds447142.736: [GC [PSYoungGen: 515825K->7027K(517248K)] 1140480K->641618K(1565824K), 0.0211740 secs] [Times: user=0.03 sys=0.00, real=0.02 secs] Total time for which application threads were stopped: 0.0237380 secondsApplication time: 0.0008020 secondsTotal time for which application threads were stopped: 0.0048850 secondsApplication time: 57.3291140 seconds447200.095: [GC [PSYoungGen: 517235K->7034K(499456K)] 1151826K->654591K(1548032K), 0.0233490 secs] [Times: user=0.10 sys=0.01, real=0.02 secs] Total time for which application threads were stopped: 0.0259740 secondsApplication time: 0.0005330 secondsTotal time for which application threads were stopped: 0.0015090 secondsApplication time: 0.0003870 secondsTotal time for which application threads were stopped: 0.0009830 secondsApplication time: 0.0001650 secondsTotal time for which application threads were stopped: 0.0009320 secondsApplication time: 0.0000790 secondsTotal time for which application threads were stopped: 0.0009570 secondsApplication time: 0.0001280 secondsTotal time for which application threads were stopped: 0.0009260 secondsApplication time: 0.0001270 secondsTotal time for which application threads were stopped: 0.0007940 secondsApplication time: 350.4612180 secondsTotal time for which application threads were stopped: 0.0070700 secondsApplication time: 17619.4182670 seconds479708.875: [GC [PSYoungGen: 499450K->4193K(508352K)] 1147007K->658558K(1556928K), 0.0232460 secs]可以看出长时间没人访问，之后再GC就死了。想了很久也想不出原因，清高人给个思路 问题补充：enet_java 写道
解决方案
tomcat是什么版本呀？换换版本再试试吧，有些是tomcat自身的bug导致的。
解决方案二：
这个我知道的，呵呵！之前我也用过jboss，具体我忘记是4.x版本了，没有遇到过tomcat死掉的情况呢。
解决方案三：
你使用的是jboss。jboss版本是4.0？
