Hi,all:
    I use tomcat as my servlet server,after several times restart,console always throw errors like:

- IOException reading index. Creating new index.
- cocoon-ehcache-1Cache: Could not create disk store
java.io.IOException: Index file D:\jakarta-tomcat-4-wsad\work\Standalone\localhost\PowerOA\cocoon-files\cache-dir\cocoon-ehcache-1.index could not created.

- RAMJobStore initialized.
And then any request will throw an exception:
net.sf.ehcache.CacheException: cocoon-ehcache-1 Cache: The Disk store is not active.


  It looks like the index file cocoon-ehcache-1.index can't be delete or read.After delete all these file,it works fine,but this will happen again after several times restart.If I disable disk cache in cococon.xconf like:
  <store logger="core.store">
    <parameter name="maxobjects" value="1000"/>
    <parameter name="use-cache-directory" value="false"/>
  </store>
This will also happen but in cocoon-files directory.

Any suggestion?
