Eclipse 崩溃并显示“无法创建新的本机线程” - 有什么想法吗? (里面有我的设置和信息)
我遇到了 Eclipse 的麻烦,它经常让我崩溃(而且通常都很迟钝),我想知道是否有人能给我任何见解。抛出的消息是“无法创建新的本机线程。”,此时系统会提示我重新启动 Eclipse。这种情况每天会发生 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 设置是从此 线程:eclipse 的最佳 jvm 设置是什么:
-startup

感谢您的帮助!
编辑:
@normalocity - 错误实际上刚刚发生(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)。这是您要求的附加信息,异常堆栈跟踪:

I'm having trouble with Eclipse routinely crapping out on me (and being generally sluggish) and I was wondering if anyone could give me any insight. The message that gets thrown is "Unable to create new native thread." at which point I'm prompted to restart Eclipse. This happens 5 or so times a day.
I'm using Ecliipse Helios Service Release 2 (with Flash Builder plugin) on:
Windows Vista Business
Processor: Intel Core 2 Duo T7500 @ 2.20 GHz
Memory (RAM): 4.00 GB
System Type: 32-bit Operating System

Thanks for any help!
edit:
@normalocity - the error literally just happened (Unhandled event loop exception), this is after adjusting my eclipse.ini (I changed Xss to 1m, MaxPermSize to 384m, Xms to 512). Here is the additional info you asked for, exception stack trace:

似乎没有足够的内存用于新线程堆栈。在 Windows 上,进程空间为 2GB。对于堆,您最初分配 1Gb(-Xms 选项),因此它从一开始就被锁定。类 (PermSize) 减去 256Mb,再减去可能高达 0.5Gb 的 JVM 开销。因此,您的线程只有大约 256Mb 的堆栈空间,即最多 64 个线程 (256/4m)。
解决方案:尝试将堆栈大小降低至 -Xss1024k 或减小初始堆大小 (-Xms)。
有关 OutOfMemory: 无法创建线程 的相关阅读
作为旁注,-XX:MaxPermSize=256m 看起来对于 Eclipse for EE 来说太小了。最好设置为 384。
干杯,
最大限度
It appears that there is not enough memory for new thread stack. On Windows, process space is 2GB. For heap you initially allocate 1Gb (-Xms option), so it's locked from the beginning. Minus 256Mb for classes (PermSize), minus JVM overhead which could be as much as 0.5Gb. So as a result, your threads have only about 256Mb for stacks, which is maximum 64 threads (256/4m).
Solution: Try to lower stack size to -Xss1024k or reduce initial heap size (-Xms).
Related reading about OutOfMemory: unable to create thread
As a side note, -XX:MaxPermSize=256m looks too small for Eclipse for EE. Better to set to 384.
Cheers,

我在 Fedora 20 上使用 Eclipse Luna 时也遇到了问题。我已经阅读了很多有关不同内存选项的内容,但仍然无法找出问题所在。这让我发疯。
最后我意识到,默认情况下,普通用户在 Fedora 上可以拥有的进程数量非常有限。 limit.d/90-nproc.conf 的内容:
将其提高到 5000 修复了我的“无法创建新的本机线程”问题。
I also had trouble with Eclipse Luna on Fedora 20. I've read a lot about different memory options and still couldn't figure out the problem. It drove me crazy.
Finally I realized that by default, the number of processes a regular user can have on Fedora is very limited. Content of limits.d/90-nproc.conf:
Raising this to 5000 fixed my "Unable to create new native thread" problems.
