我们有一个间歇性的问题挂在工作本身完成后的奴隶。在后处理步骤（？）中，我们看到的是控制台日志有以下行：詹金斯奴隶挂/詹金斯楔形
Description set: vap_current_iter-2012_03_29_19_01_03
然后什么也没有。通常情况下，它看起来就像这样：
Description set: prod_pull-2012_03_28_19_01_03
Notifying upstream build armada_Launch_prod_pull #13 of job completion
Project armada_Launch_prod_pull still waiting for 1 builds to complete
Notifying upstream projects of job completion
Notifying upstream of completion: armada_Launch_prod_pull #13
Finished: SUCCESS
我设置一个记录器为hudson.model.Run，它目前有这样的：
at java.lang.Thread.run(Thread.java:619)
Mar 30, 2012 12:44:00 PM hudson.model.Run run
INFO: galleon_allUnit #1134 main build action completed: SUCCESS
Mar 30, 2012 12:44:00 PM hudson.model.Run setResult
FINE: galleon_allUnit #1134 : result is set to SUCCESS

重复每一个挂奴隶。
主哈德森日志没有任何附加信息。
断开从站不起作用。
试图做一个有序关闭詹金斯没有任何影响（jenkins实际上似乎挂在关机）。
我们发现恢复的唯一方法是杀死tomcat进程。
胎面转储奴隶之一（他们都是一样的）是：

就如何更好地恢复或防止这种情况的任何想法，将不胜感激。
