Hi @JeremyRoberts2 , I am pleased to let you know that yes, we did add something at 100.10 to alleviate this issue for you. https://developers.arcgis.com/qt/qml/api-reference/qml-esri-arcgisruntime-loadsettings.html On the LoadSettings object, which you can set on a web map prior to loading it, you can set the featureTilingMode now. If you specify Enums.FeatureTilingModeDisabled, then feature tiling will be disable entirely in your map for all feature layers.

@ArmandoGarcia3 we did some internal testing at it looks like version 100.9 should work on RHEL 8 if you're able to use that. We'd encourage you to use the latest if possible, which is 100.10.

Hi @ArmandoGarcia3, Thanks for reaching out to the Qt team. Our installer is built on Java so this appears to be an installer issue. I've reached out to our installer team to see if they have any ideas. In the meantime, can you check to see if our latest version is also affected? Version 100.10 was just released and we're interested to know if out 100.10 setup shows the same behavior.

Hi @MarkHolm . How many concurrent count operations are you looking to run? Rather than trying to access the rest API directly, you can spin up multiple API objects and run one async task per object. Each object will persist the result once completed. I realize that's a workaround, but it might be easier to trying to reuse API tokens with the REST Api. Can you please share which specific API call you're wanting to call concurrently?

Hi @BBBAYRAM , Thanks for the info. I will bring this info to the Runtime team as a justification to reopen the Beta, but unfortunately I cannot promise anything. It is unlikely we can spin the project back up unless we hear from a few more users.

Hi @BBBAYRAM , Unfortunately we have closed this project and it never progressed out of the beta phase. I am interested to hear about your specific case and if this is something we can consider reopening the beta program for. I can say that the Beta did require full, Desktop-class OpenGL support and not OpenGL ES. Included with the Beta were some instructions on how to build a version of Qt for the target hardware that would target OpenGL, which is not the default for embedded devices. We had only tested on higher-end devices, such as the NVidia Jetson TX2 and Jetson Nano. To answer your question, no, the beta won't work on the i.MX8 unfortunately due to our OpenGL requirements.

Hi @rsharma , Is there any ArcGIS Runtime workflow you're trying to achieve with this? If not it's a bit off topic and more related to QML general programming. Generally speaking, whenever we've had to do image processing we use the QQuickImageProvider pattern, which does require a bit of C++ logic. I don't know if this directly applies to your use case, but I hope it is helpful. https://github.com/Esri/arcgis-runtime-samples-qt/blob/master/ArcGISRuntimeSDKQt_CppSamples/Maps/TakeScreenshot/MapImageProvider.h https://doc.qt.io/qt-5/qtquick-imageprovider-example.html https://doc.qt.io/qt-5/qquickimageprovider.html

@JeremyRoberts2 , Unfortunately I do not know of any SDK or server changes you can make with 100.7 to work around that memory issue. We are working hard on Update 10 to get that out to you soon!

@JeremyRoberts2 , I hear your concerns. I can tell you that we have some enhancements planned for the next release that should alleviate the issues related to the feature tiling requests getting queued up, resulting in worse performance. I am looking forward to getting the Update 10 release into your hands so both of these issues are resolved for you.

Hi @JeremyRoberts2 , Thanks for reaching out the Qt team, and especially thank you very much for the excellent reproducer app. That was a big help in looking into the problem. I can reproduce the issue with 100.7 and 100.8, but not 100.9. Are you able to try the 100.9 release and see if the problem is still happening for you? Please let me know if 100.9 works for you.

Hi Jan Tschada, No, unfortunately there is no guaranteed way to get the http service error from the Qt API. In some cases, this information will be part of the error object, and you can connect to that like follows: connect(featureTable, &FeatureTable::errorOccurred, this, [](const Error& error)
{
qDebug() << "FeatureTable error:" << error.message() << error.additionalMessage();
}); But however, it is not a guarantee that this information will be included with the error object. Let me know if this helps.

Hi Fatma Akdemir, We do have some Widgets examples apps in our samples repo. I would encourage you to take a look at those. arcgis-runtime-samples-qt/ArcGISRuntimeSDKQt_CppSamples_Widgets at master · Esri/arcgis-runtime-samples-qt · GitHub Also if you check into the templates we provide with our SDK, one of them is a Qt Widgets template. After you run the post installer after SDK installation, our templates will be integrated into Qt Creator. The widgets one will be called "ArcGIS Runtime 100.9 Qt Widgets app", or whatever version you have installed. Here is some info about our templates. Develop your first map app—ArcGIS Runtime SDK for Qt | ArcGIS for Developers The template shows a different workflow than our samples by subclassing QMainWindow and calling setCentralWidget. That might be closer to the pattern you use now.

Hi Norbert Thoden, I am familiar with parts of the stack trace, but we would need some more information to diagnose the problem. Do you know if this only happens at shutdown? It looks like __run_exit_handlers is getting invoked which is cleaning up some internal global statics we have, and that is aborting. But it is curious since the applications seems to be shutting down already. I saw this online c++ - Why does my application crash sometimes with a SIGSEGV when it gets closed? - Stack Overflow. This is a random guess, but is it possible the Runtime C++ API library is getting linked twice into the application? That library is a static library, libEsriRuntimeQt.a. The static in question is located in libEsriCommonQt.so, but it may be getting loaded/initialized twice if libEsriRuntimeQt.a is linked twice into the application somehow.

Hi Brian Keller, Unfortunately these are the limitations of Enums.FeatureRequestModeOnInteractionCache mode. It is optimized to reduce network bandwidth. If it is important to always have the latest data you should use Enums.FeatureRequestModeOnInteractionNoCache instead. We don't have any public info or guarantees about the details of the local cache when working in OnInteractionCache mode. An alternate approach would be to use Enums.FeatureRequestModeManualCache mode and call populateFromService on some regular interval. This might be better for your workflow if using NoCache mode uses too much bandwidth. Regarding the cacheMode, I don't think that will make any difference to this workflow. Using the default setting should reduce overall network bandwidth for requests that don't change. That might reduce overall bandwidth with NoCache or ManualCache modes when no changes are required.
