web应用借助于结构:spring mvc + quartz结构,部署到tomcat容器时,shutdown时的error信息: appears to have started a thread named [schedulerFactoryBean_Worker-1] but has failed to stop it. This is very likely to create a memory leak quartz的thread终止的确保,加了个servletListener,工作就是显…

1. 问题起因 我们项目中缓存模块某个实现采用了ehcache(2.4.3),当项目部署到tomcat中后,对tomcat做停止服务操作(点击eclipse的console红色的停止按钮,奇怪的是有小概率的情况不能复现这个问题??),发现tomcat不能正常停止,报错 appears to have started a thread named [xxx] but has failed to stop it. This is very likely to create a memory leak…

This is very likely to create a memory leak的错误,网上很多,原因也是各种各样,这里也仅提供一个解决的思路. 问题描述:启动tomcat时,不能访问部署的APP,显示404.查看启动日志catalina.out,只有一段描述,不仔细都找不到... 网上也搜了一大堆,都没实质性的帮助... 最后是把tomcat下logs里的所有日志都删了...然后重启,一个一个看生成的日志文件...才发现这个日志 localhost.2017-12-06.log .. 解…

ThreadLocal variables are infamous for creating memory leaks. A memory leak in Java is amount of memory hold by object which are not in use and should have been garbage collected, but because of unintended strong references, they still live in Java h…

遍历多个tomcat日志文件,找出含有ERROR 和Exception 的日志,并把该行日志输出到另一个文件中:(这里为了体现python模块导入的知识,所有建立了多个文件夹和模块) 项目结构: consetting.py: # 日志文件目录 F_PATH = r'C:\Users\shenping\PycharmProjects\Shenping_TEST\day_5\script\glive\logs' # 错误日志存储目录 D_PATH = r'C:\Users\shenping\Pych…
