This bug keeps coming back - after I get it once all Searches fail completely and the only way to "fix" it is to remove all Lucene files and force it to reindex the wiki - then some days later it happens again.

2005-09-06 13:34:59,991 [Thread-60] ERROR com.ecyrd.jspwiki.providers.CachingProvider  - Unable to update page 'Requirement_tsk_0' from Lucene index

I get it too, but completely randomly (it seems). Unfortunately, this is very hard to debug. Maybe it's some sort of a concurrency issue? Any Lucene experts around? Any new library versions? Workarounds?

I personally have never seen this problem, has anyone seen this problem occuring the last few months on the current JSPWiki releases ?

If nobody has seen it, well let us close the bug, and re-open it if the problem occurs.
