谢谢@JamesBallard1。用户报告说没有发生特定的操作，所以我不需要进行重现，除了报告说它已经运行了几个小时之外。这是我第一次看到这样的崩溃。

我们在Qt 5.15.2的Ubuntu 20.04上运行Esri ArcGIS Qt c++ SDK版本100.15。我们使用Qt Widgets API。有一些特定的元素，如ArcGISMapImageLayer和Graphics overlay。在没有任何解释或明确的用户操作的情况下，崩溃已经发生过一次。应用程序的这个区域已经运行了几十个小时，没有最近的更改。崩溃在libruntimecore深处。因为我们没有符号，所以我们不确定如何进一步调试，或者什么样的信息会有用。下面是堆栈跟踪。它似乎是在由ArcGIS运行时(或Qt)生成的线程上。线程69508中的堆栈跟踪(最近一次调用): #31 Object "OMITTED/external/qt/lib/libQt5Core.so.5.15.2", at 0x7fa61bffa688, in QTimerInfoList::activateTimers() #30 Object "OMITTED/external/qt/lib/libQt5Core.so.5.15.2", at 0x7fa61bf9f807, in QCoreApplication::notifyInternal2(QObject*, QEvent*) #29 Object "OMITTED/external/qt/lib/libQt5Widgets.so.5.15.2", at 0x7fa618aa2f1f, in QApplication::notify(QObject*, QEvent*) #28 Object "OMITTED/external/qt/lib/libQt5Widgets.so.5.15.2", at 0x7fa618a9c43b, in QApplicationPrivate::notify_helper(QObject*, QEvent*) #27 Object "OMITTED/external/qt/lib/libQt5Core.so.5.15.2", at 0x7fa61bfced5a, in QObject::event(QEvent*) #26 Object "OMITTED/external/qt/lib/libQt5Core.so.5.15.2", at 0x7fa61bfdcd27, in QTimer::timerEvent(QTimerEvent*) #25 Object "OMITTED/external/qt/lib/libQt5Core.so.5.15.2", at 0x7fa61bfdca56, in QTimer::timeout(QTimer::QPrivateSignal) #24 Object "OMITTED/external/qt/lib/libQt5Core.so.5.15.2", at 0x7fa61bfd7f2f, in void doActivate(QObject*, int, void**) #23 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libEsriCommonQt.so", at 0x7fa5f2f10ad9, in QtPrivate::QFunctorSlotObject, void>::impl(int, QtPrivate::QSlotObjectBase*, QObject*, void**, bool*) #22 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5eddf1cf1, in RT_GeoView_pulse #21 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5ee38d0cd, in #20 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5ef9e2acb, in #19 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5ef9e7e32, in #18 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5ef9eb803, in #17 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #16 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #15 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #14 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #13 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #12 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #11 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #10 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #9 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #8 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #7 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #6 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #5 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #4 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #3 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #2 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa27a43, in #1 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efa278d9, in #0 Object "OMITTED/external/arcgis/sdk/linux/x64/lib/libruntimecore.so", at 0x7fa5efbaf36c, in Segmentation fault (Address not mapped to object [0x556e00000003]) Anyways, thank you! Any guidance would be appreciated.

好的，我切换到场景，使用ImageOverlay，效果很好。再次感谢。

谢谢你@Tanner_Yould详细而周到的回复。我喜欢你的RAII的想法，并通过unique_ptr显式删除父，以确保调用光栅析构函数(它也防止了我之前错过的彩色地图渲染器泄漏)。我给了你的建议一枪，但我仍然看到文件句柄泄漏:john@john-ubuntu:~/-----$ pidof ---- | xargs lsof -p…约翰•185 r REG 0——155580 27 51804 176 /dev/shm/a6da76fc ab - 74 - 4 - fa9 - 9854 b207f04ff162.tif约翰•186 r REG 0——155580 27 51804 176 /dev/shm/a6da76fc ab - 74 - 4 - fa9 - 9854 b207f04ff162.tif约翰•187 r REG 0——155580 27 51804 176 /dev/shm/a6da76fc ab - 74 - 4 - fa9 - 9854 b207f04ff162.tif约翰•188 r REG 0——155580 27 51804 176 /dev/shm/a6da76fc ab - 74 - 4 - fa9 - 9854 b207f04ff162.tif(进程名称清单改为,)在任何情况下我会查看动画光栅的例子你引用和给它一试next. Thank you again, I'll let you know here how it goes.

我正在寻找一个问题，我有光栅和光栅层。我每隔几秒就会定期加载一个新的栅格层，并删除一个旧的栅格层。参见下面的代码。Esri::ArcGISRuntime::Raster* Raster = new Esri::ArcGISRuntime::Raster(QString::fromStdString(filename)， raster_group_layer_);Esri::ArcGISRuntime::RasterLayer* raster_layer = new Esri::ArcGISRuntime::RasterLayer(光栅，raster_group_layer_);QList colors =…Esri::ArcGISRuntime::ColormapRenderer* colormap_renderer = new Esri::ArcGISRuntime::ColormapRenderer(colors, this);raster_layer - > setRenderer (colormap_renderer);raster_layer - > setLayerId (QString:: fromStdString (guid.toString ()));Esri::ArcGISRuntime::Layer* old_layer = findLayer(raster_group_layer_->layers()， guide . tostring ()); raster_group_layer_->layers()->removeOne(old_layer); raster_group_layer_->layers()->append(raster_layer); The behavior I observe is leaked open file handles. When I call "lsof -p " on my process I see the same tif open repeatedly; this grows as time goes on. I am certain these open file handles are from the code above (I commented it out and the file list did not grow). The file handle list grows until eventually the process dies due to too many open files. What is the recommended way to delete a Raster and RasterLayer? I've tried: delete raster_layer; and group_layer_->layers()->removeOne(raster_layer); I suspect the latter is correct since it does appear to remove the image from display. Do you observe similar behavior with RasterLayer file handle leaks? Reproduction of this should be straightforward, let me know if it isn't and I can invest in a fully reproducible example. Also some other questions related to my workflow. Basically I have some sensor raster data in memory I want to throw onto the map. It changes frequently. Is there a way to just hand in a QImage and transform to the RasterLayer directly? As a workaround I write a tiff to memdisk, then create a new RasterLayer on each update. As you may guess this is expensive and hacky. Is there a way to simply say, "reload the file" or "load this other new file" so I don't need to make a new RasterLayer each time? Anyways thank you for looking at this, any suggestions are welcome! Edit: confirmed happening on v100.9 and v100.11.
