在kill -3时不生成线程转储 [英] No threaddump generated on kill -3

是否有可能kill -3/quit PID不输出任何内容，即空线程转储?我们听到了一名支持工程师的故事，想知道是否有些专家可以验证.

Is there a possibility that kill -3 / quit PID prints nothing i.e. an empty thread dump? We heard a story from a support engineer and was wondering if some experts could validate.

这是在RHEL 5上的Java 6_26上

This is on Java 6_26 on RHEL 5

推荐答案

我仅在服务器重定向到JBoss之类的stdout且stdout已重定向到/dev/null时才看到此消息，因为任何设置服务器的人都认为所有要输出到stdout的东西都已经在一个命名日志文件中了.

I have only seen this when the server redirects to stdout, like JBoss, and stdout has been redirected to /dev/null because whoever set up the server thought that everything going to stdout was already going to a named log file.
