我在一个服务里也遇到了这个问题
出错后服务自动重启了，我的原因是 在声明Logger的时候把后台服务中的Logger携程了
java.lang.Thread.sleep(Native Method)
org.apache.log4j.helpers.FileWatchdog.run(FileWatchdog.java:104)
六月 07, 2016 3:53:51 下午 org.apache.jasper.servlet.TldScanner scanJars
信息: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

private static final Logger logger = Logger.getLogger(Client.class);clsss写错了，Client.clsss在调用完就结束了，所以后台服务就出错了
