After Updation From to Juno to Kepler.But with the same configurationI did'nt face any issue.
更新后从朱诺到开普勒。但同样configuration我没有遇到任何问题。

[ERROR] Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M ...)
It's keep telling me
它一直在告诉我
[ERROR] Out of memory; to increase the amount of memory, use the -Xmx flag at startup (java -Xmx128M ...)
[错误] 内存不足；要增加内存量，请在启动时使用 -Xmx 标志（java -Xmx128M ...）
Here is my VM args
这是我的 VM 参数
What could be the issue..
可能是什么问题..
Thanks for any help.
谢谢你的帮助。

Why am I getting a java.lang.OutOfMemoryError: PermGen space?
The default maximum Permanent Generation space set by your JRE may be too small. This is unrelated to the maximum allowed Heap space. You can increase the maximum PermGen size by launching Eclipse with the VM argument: -XX:MaxPermSize=128m
为什么会出现 java.lang.OutOfMemoryError: PermGen space？
您的 JRE 设置的默认最大永久代空间可能太小。这与允许的最大堆空间无关。您可以通过使用 VM 参数启动 Eclipse 来增加最大 PermGen 大小：-XX:MaxPermSize=128m

Increase -vmargs to 512 & 1024 in eclipse.ini & close the eclipse & open it again.
在 eclipse.ini 中将 -vmargs 增加到 512 和 1024 并关闭 eclipse 并再次打开它。
Hopefully it will solve the issue.
希望它能解决问题。

This problem might also be due to there being too many apps in the launch list when you Run As ... Run on Serverin eclipse.
此问题也可能是由于您Run As ... Run on Server在 Eclipse 中启动列表中的应用程序过多。
To find out of this is the cause of the problem, you can just click Nextto see the list of apps that will be launched, instead of rushing through to click Finish.
要找出这是问题的原因，您只需单击Next即可查看将启动的应用程序列表，而不必急于单击Finish。
If you see other apps besides the one you want to launch, just remove all the unwanted apps so that only your app is selected, and then click Finish. This will require much less memory and thus not require you to Hyman up the PermGen space.
如果您看到除要启动的应用程序之外的其他应用程序，只需删除所有不需要的应用程序，以便仅选择您的应用程序，然后单击Finish。这将需要更少的内存，因此不需要您增加永久代空间。
