IOException when trying to query - intermittently

Occasionally, I get the following error when trying to run a fairly mundane
query:

ERROR 21-02 15:06:12,573 (QueryImpl.java:execute:188)  -Exception while
executing query:
java.io.IOException: No such file or directory
    at java.io.UnixFileSystem.createFileExclusively(Native Method)
    at java.io.File.createNewFile(File.java:850)
    at org.apache.jackrabbit.core.query.lucene.FSDirectory$1.obtain(
FSDirectory.java:119)
    at org.apache.lucene.store.Lock.obtain(Lock.java:53)
    at org.apache.lucene.store.Lock$With.run(Lock.java:108)
    at org.apache.lucene.index.IndexReader.open(IndexReader.java:111)
    at org.apache.lucene.index.IndexReader.open(IndexReader.java:106)

Any ideas?

Hi Jukka.
No this is linux, Fedora Core 5 (laptop, not server).

Its rare, and it always works just by restarting the workspace.

        <SearchIndex class="
org.apache.jackrabbit.core.query.lucene.SearchIndex">
            <param name="path" value="${wsp.home}/index"/>
        </SearchIndex>

(I am using TransientRepository which creates this as needed - but that was
the content at the time it puked).

It does seem like a file system related intermittent thing - windows I would
not be surprised, but linux seems like its more of a race condition?

Anyone else seen this?
Is there a way to programmatically simulate starting up the workspace
multiple times - so I can try and trap this in a unit test?

Michael.

Strange. Are you running on Windows? I've occasionally seen similar
random IO errors on Windows especially if there's a dynamic virus
scanner or some similar background tool operating.

Alternatively it could be related to some query configuration issue.
Please send the <SearchIndex/> configuration entry in the
workspace.xml file within the workspace you're querying.

BR,
