I'm using CKFinder within an ASP-Net app and while uploading multiple images at once the generation of the thumbnails sometimes fails. If I open the file browser again after the exception occurs the failed thumbnails generating fine.
The error occurs regulary when I upload more than 2 files. The files saved completly in the file system, only thumbnails are missing when the error occured. File permissions and path are right and don't vary between the attempts.
The following exception is thrown:
System.Web.HttpUnhandledException (0x80004005): Eine Ausnahme vom Typ "System.Web.HttpUnhandledException" wurde ausgelöst. ---> System.Runtime.InteropServices.ExternalException (0x80004005): Allgemeiner Fehler in GDI+. bei System.Drawing.Image.Save(String filename, ImageCodecInfo encoder, EncoderParameters encoderParams) bei CKFinder.Connector.ImageTools.ResizeImage(String sourceFile, String targetFile, Int32 maxWidth, Int32 maxHeight, Boolean preserverAspectRatio, Int32 quality) bei CKFinder.Connector.CommandHandlers.ThumbnailCommandHandler.SendResponse(HttpResponse response) bei CKFinder.Connector.Connector.OnLoad(EventArgs e) bei System.Web.UI.Control.LoadRecursive() bei System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) bei System.Web.UI.Page.HandleError(Exception e) bei System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) bei System.Web.UI.Page.ProcessRequest(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) bei System.Web.UI.Page.ProcessRequest() bei System.Web.UI.Page.ProcessRequestWithNoAssert(HttpContext context) bei System.Web.UI.Page.ProcessRequest(HttpContext context) bei ASP.secure_controls_ckfinder_core_connector_aspx_connector_aspx.ProcessRequest(HttpContext context) bei System.Web.HttpApplication.CallHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() bei System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)
