Take photo and resize - memory problem

App-type: mobile Titanium SDK version: 3.1.1 (06/15/13 16:09 f7592c1) Platform Android Device: Android physical device (samsung S2) OS: Windows Titanium Studio: build: 3.1.0.201304151600

I have a tableView with 5 to 15 rows. Every row shows a default image (about 1-10kb). When the user click the row, a popup window opens, where he can decide to abbort or to take a photo. he can choose between take a new photo, or take a photo from galery. If he decides to take a photo, the camera opens. On Success, i take the event.media and write 2 files. First image should be very small, to show it in the tableview and the second should be medium size, to send them via e-mail in the next steps. my problem is, that the "imageAsResized" method sometimes throw a memory error or before that step, the app restarts after taking the photo an click save/accept.

Titanium.Media.showCamera({
            //we got something
            success : function(event) {
                Ti.API.info('#### Camera Success');
                //checking if it is photo
                if (event.mediaType == Ti.Media.MEDIA_TYPE_PHOTO) {
                    self.dataArr['data'][targetRow.id]['saved_image'] = null;
                    self.dataArr['data'][targetRow.id]['saved_image_small'] = null;
 
                    self.dataArr['data'][targetRow.id]['saved_image'] = "pic" + targetRow.index + ".jpg";
                    self.dataArr['data'][targetRow.id]['saved_image_small'] = "pic" + targetRow.index + "_small.jpg";
 
                    filePath_big = Titanium.Filesystem.applicationDataDirectory + Ti.Filesystem.separator + self.dataArr['data'][targetRow.id]['saved_image'];

                    smallImage = resizeImage(event.media, 100);

                    if (smallFile.exists())
                        smallFile.deleteFile();
 
                    smallFile.write(smallImage);
