Hi,
Client said they did not index, all they do is searching (create
Searcher objects), I looked at 1.4.3 and think this issue can
happen in:
private static IndexReader open(final Directory directory, final boolean
closeDirectory)
syncronized(directory) {...}
if calls are coming from different Java processes (in our case
a few AppServer clusters)?
Thanks very much for helps, Lisheng

Likely your exception happened because a reader was trying to open
just as a writer was committing, twice in a row.
Do you commit (flush or close) frequently from your writer?
As of 2.1, Lucene no longer uses a commit locks -- commits are now
lockless, so you won't hit this on upgrading to 2.4.
