我們有一個間歇性的問題掛在工作本身完成後的奴隸。在後處理步驟（？）中，我們看到的是控制檯日誌有以下行：詹金斯奴隸掛/詹金斯楔形
Description set: vap_current_iter-2012_03_29_19_01_03
然後什麼也沒有。通常情況下，它看起來就像這樣：
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
我設置一個記錄器爲hudson.model.Run，它目前有這樣的：
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
java.lang.Exception

重複每一個掛奴隸。
主哈德森日誌沒有任何附加信息。
斷開從站不起作用。
試圖做一個有序關閉詹金斯沒有任何影響（jenkins實際上似乎掛在關機）。
我們發現恢復的唯一方法是殺死tomcat進程。
胎面轉儲奴隸之一（他們都是一樣的）是：

就如何更好地恢復或防止這種情況的任何想法，將不勝感激。
