Java顯示錯誤java.lang.OutOfMemoryError

我下載了Parsemis程序。這是從Java創建的頻繁的子圖挖掘程序。我在parsemis中使用的數據非常大。Java顯示錯誤java.lang.OutOfMemoryError

我嘗試在Windows10中運行java parsemis通過添加-Xmx4096M它顯示這樣的錯誤。這個問題的原因是什麼？如何解決它？

java -Xmx4096M -jar parsemis-2008-12-01.jar --graphFile=graph_all.lg --outputFile=output.lg --minimumFrequency=10%

它顯示這樣的錯誤。

你的電腦需要更多內存？ –

嘗試使用較低的Xmx值，例如2048. – Maverick

以前的評論可能都是正確的。但你需要硬數據。我會分析它 – efekctive

嘗試這樣做的塊，也許是因爲一段代碼，從來沒有超出範圍的內存空間是沒有得到釋放，作爲回報過了一會操作系統的步驟中，終止程序，並嘗試釋放內存位置。
