我遇到了 Eclipse 经常对我发脾气（并且通常很迟钝）的问题，我想知道是否有人可以给我任何见解。抛出的消息是“无法创建新的本机线程”。此时会提示我重新启动 Eclipse。这种情况每天发生 5 次左右。
我正在使用 Ecliipse Helios Service Release 2（带有 Flash Builder 插件）：
Windows Vista Business
Processor: Intel Core 2 Duo T7500 @ 2.20 GHz
Memory (RAM): 4.00 GB
System Type: 32-bit Operating System
我的 eclipse.ini 设置是从这个线程中偷来的： eclipse 的最佳 jvm 设置是什么：
-startup
plugins/org.eclipse.equinox.launcher_1.1.1.R36x_v20101122_1400.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.2.R36x_v20101222
-product
org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
-showsplash
org.eclipse.platform
-vm
C:/jdk1.6.0_25/jre/bin/client/jvm.dll
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Declipse.p2.unsignedPolicy=allow
-Xmn256m
-Xms1024m
-Xmx1024m
-Xss4m
-XX:PermSize=256m
-XX:MaxPermSize=256m
-XX:CompileThreshold=5
-XX:MaxGCPauseMillis=10
-XX:MaxHeapFreeRatio=70
-XX:+CMSIncrementalPacing
-XX:+UnlockExperimentalVMOptions
-XX:+UseG1GC
-XX:+UseFastAccessorMethods
-Dcom.sun.management.jmxremote
谢谢你的帮助！
编辑：
@normalocity - 错误刚刚发生（未处理的事件循环异常），这是在调整我的 eclipse.ini 之后（我将 Xss 更改为 1m，MaxPermSize 更改为 384m，Xms 更改为 512）。这是您要求的其他信息，异常堆栈跟踪：
