SocketException (0x80004005): An existing connection was forcibly closed by the remote host
提问by user1584120
Hoping somebody can help with this exception. Our client app can spawn up to 3 server apps (new processes) and communicates with each through TCP. These in turn spawn a jvm when prompted (server app essentially a wrapper for communicating to jvm through shared memory). When I set the memory on each jvm to be about 25gb (I have 8gb ram) it will not run any of the 3 server applications and throws the above exception. When I set it be 10gb it will run one of them but throw that exception when I try start the second jvm. The exception appears to happen when I try and start the jvm (prints logging statement just before it makes first java call) however this exception is only captured on the client side. I'm wondering if this is a stackoverflow on the server side?
希望有人可以帮助解决这个例外。我们的客户端应用程序最多可以生成 3 个服务器应用程序（新进程）并通过 TCP 与每个应用程序通信。这些反过来会在提示时生成一个 jvm（服务器应用程序本质上是一个用于通过共享内存与 jvm 通信的包装器）。当我将每个 jvm 上的内存设置为大约 25gb（我有 8gb ram）时，它不会运行 3 个服务器应用程序中的任何一个并抛出上述异常。当我将它设置为 10gb 时，它将运行其中一个，但在我尝试启动第二个 jvm 时抛出该异常。当我尝试启动 jvm 时似乎发生了异常（在它进行第一次 java 调用之前打印日志语句）但是这个异常只在客户端被捕获。我想知道这是否是服务器端的stackoverflow？

This will happen when, as the exception implies, the remote host (server) closes the connection unexpectedly. This can be due to a multitude of reasons, but typically is due to an unhandled exception on the server side. Investigate the server code and go from there.
这将发生在异常情况下，远程主机（服务器）意外关闭连接。这可能是由于多种原因造成的，但通常是由于服务器端未处理的异常。调查服务器代码并从那里开始。
