如何修复jboss中的“ IJ000305：发生连接错误”

Question

我收到“ IJ000305：发生连接错误”的警告，并带有“ java.lang.OutOfMemoryError：Java堆空间”。

即使出错，我也给出了6GB的堆大小。 我正在使用jboss服务器，sqlserver数据库。 我的服务器和数据库位于不同的网络上。 当我的服务器启动后，它可以在15分钟到2个小时内正常工作，然后出现此错误。

以下是错误日志：

Answer 1

问题是

Caused by: java.lang.OutOfMemoryError: Java heap space

这可能是内存泄漏，我首先要增加堆的大小，然后重试。 如果您继续增加而又继续失败，则可能是内存泄漏。

您可以获取堆转储，并使用Eclipse MAT对其进行分析。
