Apache Mesos 啟動一次，但一旦我關閉它就不會重新啟動

我在 redhat 6.6 機器上建構了 Apache Mesos。它已安裝到我將呼叫的目錄$INST中。

我設置$INST/etc/masters並$INST/etc/slaves擁有主人和奴隸的主機名，然後$INST/etc/mesos-slave-env.sh像這樣設置：

export MESOS_work_dir=/path/to/some/directory/$HOSTNAME/work
export MESOS_log_dir=/path/to/some/directory/$HOSTNAME/log
export MESOS_master=masternodename:5050

和$INST/etc/mesos-master-env.sh完全一樣，但沒有MESOS_master定義。

/path/to/some/directory可以由所有節點共享，也可以在我遇到的行為的所有節點上唯一。

然後我$INST/sbin/mesos-start-cluster第一次跑。開始。我可以打開firefox masternodename:5050並查看 Web UI，它顯示了所有附加的從站。

但是，如果我跑去$INST/sbin/mesos-stop-cluster.sh殺死集群，然後用 重新啟動它mesos-start-cluster.sh，它就會永遠掛起。curl masternodename:5050打開到埠的連接並永遠等待數據，但沒有數據。日誌顯示了這一點，並且從這裡沒有任何進展：

（數據有些匿名）

我第一次啟動它時它工作得很好，但第二次就永遠掛起，我不知道為什麼。它必須在某處儲存狀態資訊，但lsof沒有向我顯示它在執行期間可能會影響任何節點的任何文件！

任何想法在哪裡看或可能導致這種情況？

問題是系統的熵池已經耗盡，並且它在讀取到/dev/random;時被阻塞。它是通過編譯一個新版本的cyrus-sasl庫來使用/dev/urandom而不是 解決的/dev/random，並將我的 mesos 連結到那個。
