OutOfMemory將上載文件上傳到運行在Websphere上的AppCenter Liberty

Question

我創建的最新環境（實際上是多個）似乎都有同樣的錯誤將上傳文件上傳到MobileFirst中的應用程序中心。如果我重新啓動websphere並重新部署，他們會通過。

我運行WebSphere自由8.5.5.7

jvm.options設置爲：
-Dcom.ibm.ws.jmx.connector.client.rest.readTimeout = 180000
- Xms1024m
-Xmx1024m

APK尺寸圍繞每個37MB，
部署USI ng本地java工具：在ANT內調用com.ibm.appcenter.Upload

Answer 1

看起來由於某種原因，Websphere內存不足。

嘗試在APK文件中查找元數據時發生內存不足。在這個時候，它會在內存中保存37 MB的APK文件（即74 MB），並試圖解壓縮部分APK文件以提取清單。除非提取的清單很大，否則不應該導致OutOfMemory。通常它很小。

但是，你說你使用com.ibm.appcenter.Upload工具。如果您使用此功能並行上傳多個APK文件，則可能會導致內存問題，例如並行10個這樣的文件是740 MB，那麼您可以輕鬆達到您設置的1GB堆空間限制。

內存使用情況還取決於在該時間點Web服務器中發生的其他情況。例如，每個嘗試下載37 MB apk的設備都需要37 MB的內存。

如果問題僅出現在特定的APK文件中，但與其他文件不同，我建議聯繫IBM支持人員分析這些APK文件。
