Summary

Opening a document that contains a particular type of image may cause the Laserfiche client to stop responding. Additionally, the Laserfiche Server will utilize 100% of the server's processor.

Cause

Thumbnail generation for certain types of images can overload the Laserfiche Server. The compression algorithm works better on some images than others. On the problematic images, the compression algorithm to create the thumbnails cannot completely finish compressing the image and becomes trapped in a infinite loop. There is no quick way ahead of time to tell what types of images may cause this issue short of running the compression algorithm.

Resolution

This issue is resolved in Laserfiche 7.0.3 and later. Please upgrade to the latest version of Laserfiche.

Workaround

Disable the Thumbnails view for documents that cause this issue. You will then be able to open the document.

To hide thumbnails in the Standard Layout Document View

• Make sure that the View Thumbnails toolbar button is not selected. If the View Thumbnails toolbar is currently selected, then simply click on it.

To hide thumbnails in the Classic Layout Document View

• If you would like to hide thumbnails and both panes are in use, then you will first need to determine the pane in which it is being displayed. From the View menu, open the appropriate menu for that pane (Left or Right View menu). Select None.
• If you would like to hide thumbnails and only a single pane is being displayed, then you will need to select another view to replace the Thumbnails view. From the View menu, open the Left or Right View menu, and then select Image, Text, or Fields.
