.net 多线程炸栈问题记录

问题现象

1. 预：开启线程超过1000多；
2. 程序运行时抛出异常，且未开启预期1000多线程；
3. 程序运行时，cpu、内存占用均较小；cpu 30%，内存 300M；
4. x64程序运行正常，x86程序运行则报 'System.OutOfMemoryException'；

错误：

Exception of type 'System.OutOfMemoryException'

启动采集线程时异常 
 System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was thrown.
   at System.Threading.Thread.StartInternal(ThreadHandle t, Int32 stackSize, Int32 priority, Char* pThreadName)
   at System.Threading.Thread.StartCore()

   at ***.StartThread() in ***.cs:line 234
   at ***.<>c__DisplayClass13_1.<CreateDeviceThread>b__0(Device d) in ***.cs:line 165
