Subject [jira] Created: (JCR-1058) Index segment lost after consistency check
Date Tue, 14 Aug 2007 08:57:30 GMT
Index segment lost after consistency check
------------------------------------------

                 Key: JCR-1058
                 URL: https://issues.apache.org/jira/browse/JCR-1058
             Project: Jackrabbit
          Issue Type: Bug
          Components: indexing
    Affects Versions: 1.3
            Reporter: Christoph Kiehl
            Priority: Critical


On one of our server it seems like a whole index segment got lost because all nodes that were
added just before the crash where not in the index anymore an we got this in out log file:

A bit later while trying to commit a transaction the following exception was logged:

[...]

This leads me to the assumption that one of those indexes listed in the field "indexes" in
MultiIndex was somehow deleted from the file system.
