Hudson收银台卡在“git fetch”上

我使用的是git版本1.6.2.2.1669.g7eaf8

控制台输出—它连续几天都在这里:

    Started by user anonymous

    Checkout:workspace / C:\hudson\jobs\Group1-git\workspace - hudson.remoting.LocalChannel@3d858159

    Last Build : #63

    Checkout:workspace / C:\hudson\jobs\Group1-git\workspace - hudson.remoting.LocalChannel@3d858159

    Fetching changes from the remote Git repository

    Fetching upstream changes from ssh://git@git/devl.git

    [workspace] $ git.cmd fetch ssh://git@git/devl.git +refs/heads/*:refs/remotes/origin/*

以下是卡住线程的堆栈跟踪:
