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 与每个应用程序进行通信。当出现提示时，这些又会生成一个 jvm（服务器应用程序本质上是一个通过共享内存与 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引发上述异常。当我将其设置为 10gb 时，它将运行其中一个，但当我尝试启动第二个 jvm 时会抛出该异常。当我尝试启动 jvm（在它进行第一次 java 调用之前打印日志语句）时似乎发生了异常，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？

正如异常所暗示的那样，当远程主机（服务器）意外关闭连接时，就会发生这种情况。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。
