Resolving the problem

This issue was reported to Quality Engineering as SPR# DVDI7ED9EF and has been fixed in Domino releases 8.5.2.


NOTE: In some cases, this fix does not address the issue. If this is the case, as a temporary workaround, identify the problem database and delete the index.

As a preventative measure, enable the feature described in SPR MTMY5J2JX8 by setting the notes.ini "FTG_ENABLE_GTR_KEY_CHECK=1". This will identify corrupted data contained in any of the GTR KEY files.

In most cases, rebuilding the full text index resolves the issue. As most corrupted indexes are associated with very large databases, it is best to target the problem database for rebuild. From server console, run the following command: load updall -x <name of database>.nsf

Workarounds
As a workaround, some administrators deleted the full-text index of the affected mail files, and then did not recreate the index until the server was upgraded to a fixed release.

Requested steps to collect critical data during workaround:
1) Determine, if possible, what exact query was being performed at the time of the failure. Debug to capture such information would be "DEBUG_FTV_SEARCH=1".

2) Save off the full text index associated with the database where the query was performed by moving it to another location. As size has been a factor in previous occurrences, create an archive of the full text index directory and all its' contents.
