Grails在啓動時被卡在新服務器上

Question

我剛剛獲得了Ubuntu 12.04LTS的全新VM（Proxmox 1.9）實例。我當時以下：

1. 安裝了Sun的Java JDK 7和設置JAVA_HOME
2. 下載的Grails 2.2.0和設置GRAILS_HOME和PATH

運行

$ grails 

是始終堅持上：

| Loading Grails 2.2.0 

或有時它會盡可能

| Configuring classpath 

我只能終止使用kill -9 <pid> /過程： 我剛剛以下異常太：我已經試過

$ grails   
Exception in thread "Reference Handler" java.lang.IllegalMonitorStateException 
    at java.lang.Object.notifyAll(Native Method) 
    at java.lang.ref.ReferenceQueue.enqueue(ReferenceQueue.java:68) 
    at java.lang.ref.Reference$ReferenceHandler.run(Reference.java:146)

$ javac -version 
javac 1.7.0_11 

尋找任何系統日誌，但沒有運氣...只是this Java log trace ......很長一個 http://pastebin.com/raw.php?i=YEesBGXn

與以下JAVA_OPTS運行

$ echo $JAVA_OPTS 
-verbose:gc -XX:+PrintGCDetails -Dgrails.env=development -server -Xmx512M -XX:MaxPermSize=256m 

顯示非常不尋常的垃圾收集，比我的本地機器上更加迅速，超過30次，在短短的第二!!!!

任何關於什麼可能是錯誤的想法嗎？

謝謝一堆，

阿米特。

Answer 1

已解決。

這是這裏所描述的Proxmox的虛擬機的問題：http://forum.proxmox.com/archive/index.php/t-6998.html

它有助於使機器更多的CPU功率。

Answer 2

這不是Proxmox的問題，它是OpenVZ的問題。如果你使用Proxmox，我建議你帶一個kvm實例。但是，似乎OpenVZ與IBM JDK一致，也許您可​​以嘗試IBM的Java運行時。你最好不要在OpenVZ中運行JVM。
