Summary

During the indexing process, the Laserfiche Search Engine can become unstable when optimizing large search catalogs.

Cause

The Laserfiche Search Engine performs internal optimizations when dealing with a large lflink.idx file. In certain situations, the optimization may not correctly modify the lflink.idx file, resulting in instability the next time the search engine needs to perform the optimization process.

Resolution 1

This issue is resolved in Laserfiche 8.1 and later. Please upgrade to the latest version of Laserfiche.

Resolution 2

There is a hotfix available for Laserfiche 8.0.2. The fix includes updated versions of LFFTS.exe (version 8.0.2.840) and QRcmd.exe (version 8.0.2.840).
