Summary

The Laserfiche Server may become unstable in a specific situation involving an invalid .idx file.

Cause

This error can occur in certain situations when the Laserfiche Server detects an invalid .idx file. It will only occur if you previously applied one of the following hotfixes:

• LFEng.dll (version 7.2.1.425)
• LFEng.dll (version 7.2.1.430)
• LFEng.dll (version 7.2.1.435)

Resolution

There is a hotfix available for the Laserfiche Server. The fix is an updated version of LFEng.dll (version 7.2.1.440).

Important: This hotfix includes changes made in two previous LFEng.dll hotfixes (7.2.1.410 and 7.2.1.425) that affect the external components of a Laserfiche repository. If you wish to directly update the release version of LFEng.dll (7.2.1.407) to LFEng.dll (7.2.1.440), you must also perform the necessary updates to your SQL database table structure, delete your repository's SEARCH folder, and re-index your repository.
