arcengine异步线程批量处理影像纠正崩溃

IRasterGeometryProc rasterPropc = new RasterGeometryProcClass();
rasterPropc.Warp(sourcePoints, targetPoints, transformtype, traster);
rasterPropc.Resample(ResamplingTypes, cellsize, traster);
rasterPropc.Register(traster);
rasterPropc.Rectify(savePath + @"\" + rasterName + ".tif", "TIFF", traster); //异步线程执行到Rectify程序就崩溃了，单线程就能正常运行
